When professor Dr. Jayakrishnan needed an intern to join the NPTEL Data analytics team, he struggled to find the right candidate – one with the skillset and knowledge needed to succeed in the role. He received a number of applications, however, the applicants were not well versed in Data structures and Algorithms. Moreover; screening out the unqualified applicants proved to be a time-consuming process. Dr. Jayakrishnan decided to turn to CodeChef in order to get a reliable candidate pool, a pool that was sure to have the basic Data Structures and Algorithms knowledge that he was looking for.
Through the help of the CodeChef team, Dr. Jayakrishnan was able to access a list of students who were already CodeChef Certified in Data Structures and Algorithms. Since every candidate met these criteria, the need for independent DSA testing was eliminated which saved both time and effort for Dr. Jayakrishnan.
“My primary goal was looking for a Data Analytics intern. In that, data structures are pretty important. If you are a good programmer, you should be very clear of your data structures, it’s as simple as that. The better you are at it, the easier it will be for you to code and solve problems,” said Dr. Jayakrishnan, “Knowing that candidates have scored certain marks in an exam or a particular assessment test it definitely is an advantage when it comes to hiring. It is also advantageous to the candidates.”
Ultimately, Dr. Jayakrishnan selected three outstanding candidates who each had their own story.

Our leaderboards include coders from all kinds of backgrounds… even accounting! CodeChef talked to Taranpreet Singh, a coder and former CA student who traded his lucrative career as a Chartered Accountant for the thrilling world of programming, about his experiments with competitive programming and his journey so far.
As early as 10th grade, Taranpreet became interested in HTML programming. “At that time, designing HTML forms was a novelty,” he said, “My curiosity about where form data ends up, led to me not only learning PHP, but even developing a full-fledged online service website.” Unfortunately, the project was later dropped and Taranpreet fell victim to a common problem for Indian programmers, a lack of guidance and a good internet connection.
“I sometimes thought this was the end of my coding,” he continued “But destiny had other plans. In 12th I came across a programming competition called Eureka at CMS Lucknow, the turning point because it required C++ or Java. At this point, I explored Java, and won the competition.” Taranpreet attributes his win to the support of the IP dept. head of his school, who provided invaluable help and guidance when this young programmer needed it most.
This first win was only the beginning for Taranpreet. The Standard 12 (Higher Secondary Certificate) exams loomed large as did the CPT (Common Proficiency Test that all aspiring Chartered Accountants in India appeared for). “Google Codejam came in the way of my resolution and I found myself participating in a round (1A) two days before my Boards exam. Months passed and the day I attempted CPT, I joined CodeChef,” he explained. He has never looked back since.
Soon enough Taranpreet found himself at a familiar crossroads. “I had been pursuing CA, but I was spending a fair share of time towards developing programming skills, with no clear idea of how to utilize them,” he confessed, “It was not that I disliked CA, I was reasonably fine there, but I liked programming more. It was easier to stay up at night programming than solving taxation problems.” At this point, Taranpreet realized that he wanted to pursue programming. “My performance in Chartered Accountancy was not the best, but I was doing quite good on CodeChef, better than I had expected. So, I decided to switch, because I realized I’m much better here, than Accountancy. So, I myself made the choice.”
Fortunately, Taranpreet’s family did not oppose his decision, allowing him to make a smoother transition. “It came as a surprise to them, even though they already knew I was better off in programming. They took the change really well, for which I am still grateful,” he admitted. He is also deeply grateful to his mentor who provided guidance, “I had been studying CA, mostly self, so the only teacher aware about me switching is my school, IP department head, Mrs. Ambica Soni, the one who always guided me and supported me to grow into who I am today. She was, as she is always, supportive of my decision. I am quite lucky to get her as my mentor.”
Has becoming a dedicated programming student changed Taranpreet’s attitude towards Competitive programming? “In essence, no,” he asserted, “I still do programming with almost same attitude and approach toward computer programming.” But there are positive changes in his life that impact his work. “Now, I can give much more undivided focused time to programming. Earlier I had to divide time, and there was stress too. Now I feel quite relaxed and can focus on programming as much as I want. College environment means I have friends doing programming and not doing accounting, which is another thing that changed for good. So, all in all, I have no regrets switching. Life has changed for the better. I am developing my skills, and doing other things too, which I had to leave because of CA.”
As a six-star coder at CodeChef, Taranpreet has plenty of insights for anyone interested in competitive coding, “Don’t be afraid of Wrong Answers or Time Limit Exceeded or Runtime Errors” he advised, “There’s a well-said rule that we either win, or we learn. We lose only when we do not learn. If you get WA or TLE, it is not something to be depressed about, but an opportunity to learn. The person who never got WAs has never tried anything new.”
To those contemplating a career shift like his own Taranpreet advised, “Be sure about where you want to go and visualize your future. It is quite easy to decide to leave a field because you are frustrated, but quite hard to find a field which you love, where you can have a future. People may say, ‘grades don’t matter’, but don’t always believe them. Grades are not the most important factor, but they can help provide better opportunities. No matter what field you choose, if you have a passion for the discipline as well as the willingness to learn and cultivate the skills needed to excel, then you can be successful. But hard work is very important, especially in programming, as you will be competing against people who have had an earlier start and are much more experienced than you are.”
We’ll leave you with Taranpreet’s parting words which are wise beyond his 19 years:
“You can pursue your passion, with or without your job or education. It’s never too early nor too late to make choices. I don’t know what situation you are in, but I would like you to ask yourself a question. Are you happy?”.

At CodeChef, we constantly stay in touch with CCDSAP holders to make the experience better for you and to fine-tune the certification. We spoke to Avjot Singh, a CCDSAP Foundation Level Certificate holder who is placed at Cleartax as an Intern Software Developer. We asked him about his CCDSAP experience and his tips for aspiring candidates.
Pure interest! Avjot was actually studying at the Delhi Technological University to be an Electronics Engineer, but his career took a sharp left turn in his second year when when his interests expanded to include Artificial Intelligence and Machine Learning. As he learned more about these subjects, Avjot realised that he could be a better student of these disciplines by investing some time and energy into learning the basics of computer science.
In an effort to learn more about how he could strengthen his DSA skills, Avjot began some dedicated research on the subject. Soon enough his journey of internet research led him to CCDSAP and he knew it was the right path for him. Avjot didn’t know anybody who had taken the test, but he was confident in the CodeChef name and was happy with the detailed instructions and information he found about the certification.
Diligence and practice are the only secrets according to this young developer! He thoroughly studied the practice materials and explored the mock tests in order to prepare for the test. As a student with no previous background in computer science, he started readying himself for the test around two months before the exam and he recommends that candidates work on at least 5 problems a day. Avjot found himself sufficiently armed for the foundation level certificate exam after studying the materials provided, but his advice to anyone considering the advanced level is to venture out and find more problems and mock tests to work on. “Be confident in yourself, and be clear with the fundamentals before jumping straight into complex problems,” he said.
Avjot certainly thinks so! He had been impressed with the study materials before, from a learning perspective, but once he began his internship, the software development intern found that much of what he had studied and been tested on, could now be practically implemented into his day-to-day assignments and responsibilities. Avjot is now considering appearing for the advanced certificate exam to take his knowledge and abilities to the next level.
The next CCDSAP exam takes place on the 20th of January. Check this link for details and get in touch if you have any questions for us!
For Sujeet Sawala, an engineering student from Pune, tackling programming sets in front of a screen held as much interest as weaving past pawns and bishops on a chessboard. But it was the drive to learn more each day that fuelled his passion to be a better coder. Sujeet never wanted to start his job hunt but armed with his humble and dedicated approach towards programming, and learning on the whole, today he is placed in Directi through his CCDSAP certification.
But his journey started a long time back, during his college days, where he explored online contests and took to competitive programming like a fish to water. Here is an excerpt from the session we had with Sujeet about his experience with competitive programming.
Get to know me!
1. Tell us about yourself!
Hi. I’m Sujeet. I’m currently studying Computer engineering in my final year at Pune Institute Of Computer Technology, Pune. I am interested in programming and like solving complex problems. I also enjoy playing Chess. I’m an Internationally rated chess player with a FIDE rating of 1725.
2. When did you actively begin competitive programming? What did you like about it?
It was during my 3rd Semester that I explored contests with online judges and also ACM-ICPC. Since then, I gradually and actively started competitive programming. I especially liked the data structures and algorithms part of competitive programming and the challenges they throw. The logical abilities developed by attempting and overcoming those challenges are always helpful.
About CCDSAP
3. What was your motivation behind taking the CCDSAP?
I regularly participated in CodeChef Long Challenges. I was placed first on the college leaderboard. I was particularly interested in testing my skills and knowledge in a program which would also provide me a certification. That was one of the motivators for taking the CCDSAP. I was happy to learn that I scored 1000 out of 1000 in the CCDSAP in the very first attempt!
4. What specific feature did you like most about the CCDSAP? (Is there anything different that isn’t offered in other certifications?)
According to me, CCDSAP is the only program that offers certifications in Data Structures and Algorithms through programming contests. This makes it a unique certification program.
5. How did you prepare for the CCDSAP? (Any tips for beginners?)
I regularly used to practice algorithmic problems on various online judges like CodeChef, Codeforces, Hackerearth, Hackerrank, Lightoj etc. This ensured that my preparation for CCDSAP was thorough.
6. Tell us in brief about your interview process with Directi!
My interview process consisted of three interviews based on Data Structures and Algorithms. After I cleared these rounds, there was a final technical interview round. It was based on the projects done, and computer science related concepts like operating systems, databases, networking, etc.
Feedback
7. How can the overall CCDSAP exam experience be improved?
I felt the level of questions could be upgraded a notch higher so that the CCDSAP could gear up to be even more challenging.
8. Would you recommend the CCDSAP to friends/colleagues? If so, why?
Indeed. It is a good program to test one’s skills and knowledge across a wider community. The certification is a valuable one. Moreover, it helps get an interview with Directi 
Cheers!

On the eve of Women’s Day, we had the opportunity to interact with a talented female coder from India, Anushi Maheshwari (anushi), whose coding prowess and unflinching focus is breaking gender boundaries. We all have a different story about how each of us started to code, and this time we bring to you Anushi’s coding journey. As a girl who learned programming skills in school, Anushi tells us of the sheer determination and hardwork that has made her achieve success in this field dominated by ‘hims’.
Tell us something about yourself!
I am a final year student pursuing Electronics Engineering at Harcourt Butler Technical University, Kanpur.
When and how did you develop an interest in coding?
I knew JAVA since 10th grade but because of lack of a personal laptop and an internet connection, it was very late before I started competitive coding.The first challenge I participated seriously was the October Long Challenge 2016 when I was 18 but it was during the previous year’s summer vacation when I had better internet at my disposal that I spent improving myself, actively participating in May and June Long Challenges.
What sparked your interest in the field of competitive programming?
I always had a liking for it. When I first learned programming, I used to think of the best way of doing that and that’s how I went forward. Later I was fascinated with the amazing CodeChef Platform. For me, the best thing about CodeChef is their long challenge and goodies I also like the concept of hacks on Codeforces.
Any obstacles that you faced?
The coding environment is something that hindered my growth because I couldn’t find anyone to help me with the problems I faced initially and the major reason behind this was that there were not many girl coders (and only a few boys were good in CP) in HBTI. Another roadblock was my branch (Electronics Engineering). Till today, I have a tough time juggling between the 75% attendance required in Electronics classes and my self-taught Computer Science subjects. But when so many people tackle such issues, why can’t I? 
How did you overcome these obstacles?
It took me a while to realize that no magic is going to happen to help me understand algorithms. I had only me. I made a habit of not giving up on any topic until I understood it. I repeated read about the topic from different sources, ran that code in debug mode and saw if I made any progress. If not, I turned to messaging some great coders on Codeforces and I can bet you that 2 out of 5 are always there to help you if you ask a genuine doubt (not a problem of running contest).
Your views on the gender imbalance in competitive programming?
There is no doubt in the fact that there are very few women coders (only 3-4) in top 100 but I think CodeChef is doing it’s best in reducing the gender diversity by giving some extra opportunities to women
Your message to other women in the field?
The best way to learn to code is solving problems. But don’t always solve easier ones, try to grasp something new with every problem you practice. For this, I think it’s better to practice those next level problems which you were unable to do in the contest other than randomly selecting by yourself. Also, you can connect to me anytime for problems you face and I assure you of my reply (It could take a day or two if I am busy with other stuff but not more than that).

For Istasis Mishra (Codechef profile, Codeforces profile), a class 12 student from Kolkata, India, competitive programming opened the doors to a world of exciting and unending potential. Istasis first discovered Chef and his contests when he participated in the May Cook-Off 2016. And just yesterday, Istasis propelled himself into the league of coders after a commendable performance in the February Lunchtime 2018, achieving his best ever CodeChef rating in the process!
Here’s what the young boy, who aspires of representing India at the ACM-ICPC World Finals one day, has to share:
It has been a wonderful journey for me; one full of ups and downs ( you can see that in my rating graph) and also very humbling. I have met a lot of new talented people, made numerous new friends, learnt a bunch of new things, paved the way for new opportunities, experienced competition and collaboration and so much more. The list is endless!
It all began when I scored poorly in Computer Science in my half yearly school exams. I didn’t like Computer Science at all. I had no interest in it. I was more into sports. The principal used to teach our class and I had fallen down a lot in her eyes by scoring a mere 52%.
I knew I could not study unless I like it and I started googling stuff to get myself interested. And obviously I googled the most cliched “How to make money by programming?”. I landed on TopCoder where they hold competitions based on design and development and give out cash prizes to the winners. I went to the Algorithms track and saw that the problems were very interesting. I always had a knack for solving problems but there, it was truly enlightening. Yes, I obviously made very trivial mistakes back then. For example, my first submission had prompts like “Please, enter the integer: “, etc. Also, it took me about a month to understand what “test cases” mean and that is why I stuck to TopCoder for a long time even after knowing about CodeChef. Yes, the beginning was rough and intimidating as it is for everyone, but thank god, I didn’t give up.
Now looking back after one and half years of experience, I think it seemed elegant back then and I wanted to explore more. What started out as a search for marks (and money maybe) ended up in me finding my true passion.
The funny part is, I did not even know that I was doing competitive programming and that there are competitions like ICPC or IOI. I just did it as a hobby. I used to solve TopCoder problems all the time. But the great mistake I had done was that I was afraid of taking part in the competitions.
I started participating in competitions only one year after solving the easy problems. On looking back, it was my acquaintance Vatsal Sharma who told me that I am actually doing CP and that there is more to it than I think. I learnt that through Olympiads I could get admission in colleges and enjoy many other perks, and the best thing is that I was already a bit experienced when I got to know about it. At that point in time, I used to do it very casually and that led to me getting a very low rating on Codeforces and CodeChef.
In August 2016, I had my first onsite competition, Procon Junior in IIIT Delhi. It was a great experience, and I was motivated by meeting so many like minded people. I participated in ZCO too and started doing CP seriously from thereon.
Unfortunately, I didn’t make it past INOI that year but I took that as a challenge and practiced even more to guarantee myself a place in IOITC in 2018. I am really happy that I could make that happen. I can proudly say that this was the biggest breakthrough for me: cracking INOI 2018. I wouldn’t say I am a very good competitive programmer; in fact I have a long way to go to be “good” and I will still strive to be better.
(P.S Obviously, that 52% increased to 100% in my final exams 
)
Overall, there were always ups (making it to IOITC ’18, getting selected for IPC Camp, high ratings, good ranks, winning Lord of Code, etc.) and downs (low rating, missing out on IOITC ’17, etc.) along the way but what matters is I do not let them affect me and still love solving problems. I do not care if I make it to IOI or not, I am happy to be doing what I am and will always strive to improve myself.
My only tip would be to just practice and enjoy problem solving.
I have explained it elaborately here: https://discuss.codechef.com/questions/104710/an-advice-for-competitive-programming
CP has made me a better problem solver and that is definitely a plus point. I would get good marks without studying much because I was able to solve problems fast. Problem solving also helps solve real life problems. Doing CP and getting good ratings and ranks also earns you recognition.
Above all, it has helped me make my dream come true, to pursue a career in research in Computer Science and that too in one of the best institutes there possibly is in India, Chennai Mathematical Institute.
CodeChef has gone a long way in helping me practice and keeping my morale boosted. It has also provided us with Discuss where we can come together, collaborate and help each other. I have learnt a lot from the problems on the platform as well as the Discuss posts. Initiatives like IPC Camp and ICPC for Schools have also helped me stay motivated to a great extent.
CodeChef has also given my school the opportunity to be a part of the Campus Chapter initiative. This led to the formation of a Tech Club from which I am sure more talented competitive programmers will emerge. I hope I can give back to the community as much I have gained from it.

We wish Istasis all the very best in his endeavours and hope he keeps the competitive programming fire in him burning for a long long time. Are you intrigued by his story? Did you find your calling in CP too?

Rishik Sood is studying in Class 12, Amity International School, Mayur Vihar, New Delhi. When asked, he readily shared his preparation experience for INOI and highlighted some vital tips for those who are starting to prepare for the same.
I started CP very late, around 6 months before INOI. The initial months were of course very scary. I struggled really hard (around a month) to get past the easiest questions . But then I met Udit, and he introduced me to an extremely talented group of programmers and mathematicians.
After joining this group, my journey initially became even hard because these guys were just too good. But soon there came Aulene senpai with his amazing guide to INOI preparation. This small guide introduced me to really good questions and that’s where I started to pick up CP concepts. Initially, to do CP, I would really recommend joining a close group of people who do CP. I was helped a lot by guys like Istasis Mishra, Aulene De, Udit Sanghi, Vatsal Sharma, Rajarshi Basu and others in the “Coders’ Den”.
Anyway, some 1-2 months later came ZCO judgement day. ZCO wasn’t really hard. I’m pretty pretty sure I messed up but getting 100+ was not at all a tough job. Cleared ZCO and nearly ZIO. After this, I realised how the level rises from ZCO to INOI. I had to work harder than before if I had to make it to IOITC. So slowly but surely I started preparing for INOI. My key resources were Codeforces, CodeChef and USACO along with some others like SPOJ. I did these pretty well, and became much better than before in a short span of time. For people reading this, keep doing USACO religiously. I cannot stress enough that they have problems that are gold for learning interesting concepts. I did USACO till the day before INOI.
Soon came INOI judgement day. I was not the most confident person but I was pretty sure I’d make it. So I sat to give INOI. I did the graph question pretty quickly without any issue and then faced a somehow intermediate level DP question. Well, I panicked and wasn’t able to do it even though I pretty much knew the solution 10 minute into the question.
I’d like to finish by giving some final pointers specific to ICO as far as I’ve learnt about it:
Learn Python + CPP/Java. People can argue that CPP is a much more used language but in my opinion when it comes to ZCO, no language is better than Python. Easiest codes can be written quite quickly.
Know your language well and be completely comfortable in it before ZCO.
If you’re learning CPP have the STL at your tips.
If there is any onsite workshop or competition like Procon Jr. do attend it. That greatly reduces the onsite stress.
Don’t panic when giving on-site contests. I suffered quite a lot during INOI.
Read the questions well and solve them on paper first. You needn’t be the first person to do these questions so just take your time and ensure you know what you’re going to code. Include all edge cases on the paper.
Implementing questions in practice is a debatable topic, but I’d say if you are solving 10 questions, you should implement at least 4-5.
Thank you!

Unlike most participants, SnackDown 2015 was not my first SnackDown. I had also participated in the first edition of SnackDown (SnackDown 2010). I came 32nd (of 74 teams!) in the semifinal round and hence, of course did not qualify for the finals (in that year only top 7 qualified and each team had 3 members). While disappointed, I remember feeling very excited and inspired by the idea of an annual Indian onsite contest. I kept asking Anup for details of the next edition. And hence, was very disappointed when there was no SnackDown the next year or the next to next year…
Finally, SnackDown 2015 was announced. After 5 long years, I was still as excited to be participating in it. I teamed up with Deepa Panwar to form team ancalagon (aside: We were tired of all team names being “good” names. We decided on a darker team name. Ancalagon is the largest of dragons with the villain in The Silmarillion). We scraped through Round 1A even though we managed to solve just one problem. We were severely out of practice and tried to practice a bit before the elimination round. The quality of problems even in these rounds was great (even better than the Cook-Offs).
The elimination round was an eventful one. We solved the first 2 easier problems in less than 30 minutes but struggled with the 3rd problem, which required careful implementation. After trying a lot, we managed to get it accepted. We finished at a distant #82 and were sure would not qualify for the finals (top 25 Indian teams). Luckily, it turned out we just about qualified.
We could not practice much after that as we were quite busy – our final semester of M. Tech at IIT Bombay was approaching its end. In fact, our MTP (The final Thesis presentation) was just a day before the finals. We raced against time to complete the exit formalities at our college. As the contest was in Mumbai – just a few kilometers from our college, we managed to arrive late at night before the finals.
It made us miss the pre contest events. 
The event itself was extremely well organized. I had participated in ICPC World Finals at Ekaterinburg, Russia in 2014. The arrangement and facilities at the SnackDown Venue reminded me of the world finals – it was that good. All teams stayed at the famous Marriot Hotel and all travel facilities were arranged by Directi. The contest environment was awesome too – with large screens showing the scores. I loved how snacks and coffee were being served during the contest.
Coming to the contest itself, since we were out of practice for a long time, we had to decide on some good strategy to even have a chance at being the Indian Champions. In competitive coding, there is always a tradeoff between accuracy and speed. Unless you are tourist or Petr (or in Indian context – unless you are Sumeet Verma or Surya Kiran ), you have to thoroughly test your solution before submitting. I usually go for accuracy over speed.
However, looking at the top teams at the finals, I estimated that we were all roughly the same level and the champion will be decided on the penalty (and not on number of problems solved). Also, SnackDown has ICPC type scoring system. Which meant the time at which one solves the first few problems have a huge impact on the total penalty. Suppose, a team can solve 4 problems taking 15, 20, 30 and 60 minutes of computer time, the total penalty will be 15 + 35 (second problem will be solved at 15 + 20) + 65 + 125 = 240. Now, if the team decides to sacrifice accuracy for speed and solve the first 2 problems 5 minutes earlier each (by perhaps not testing on a lot of cases), the penalty will be: 10 + 25 + 55 + 115 = 205. A saving of 35 minutes of penalty time! Now even if they get a penalty on the easier problem because of lack of testing, the team will still be ahead of their usual penalty by 15 minutes.
That was our plan going into the finals – we will solve the first couple of problems as fast as possible and hope that the tradeoff works in our favor. And it did. 
We solved the first 3 problems in under one hour. For the next problem, I had underestimated the difficulty of one of the problems and kept trying it. Luckily Deepa spotted the correct problem early and we decided to switch to it. Despite incurring a WA on one of the first 3 problems, we were well ahead in terms of penalty. So, we spent some time on the fourth problem and caught quite a few bugs in it before submitting it at about 2 hours into the contest. Our estimate was right – as many as 8 Indian teams solved 4 problems and the winner was decided on penalty. And we finished almost 49 minutes of penalty time ahead of the second placed team.
Overall, it was a very fun and exciting contest and we enjoyed every moment of it. This year it is back and will be bigger than ever as even the global top 25 teams will be invited onsite. I would like to end this with one observation – many people don’t register for such contest as they feel they are “not that good” at competitive coding. My advice is – don’t think that, just participate in as many contests as possible and have fun. Who knows, you may come 32nd in one edition and win in the next .

And it’s time to meet the third member of team “stronglyConected.” Meet Akul Sareen. Akul here shares her thoughts on ACM ICPC 2016 – 2017 World finals and how his preparation for it. For any aspiring programmer out there, these are some true words of wisdom.
Team name: stronglyConnected
Team rank: Kolkata regional: #3
Q. How old were you when you started programming and what got you started in programming?
A. I was in Class 12. I came across project Euler and liked the fact that I could come up with some idea and make a computer do the dirty work for me.
Q. What inspired you to get into competitive programming? Were you passionate about it since school or anything special in college?
A. It was fun, and that was enough motivation for me to get started.
Q. How to start preparing for ACM ICPC for those who are new to algorithms and competitive programming? It would be great if you could share your journey from a beginner to a World Finalist today.
A. Pick any online judge, sort the problems by most solved and start practicing. Whenever you come across any problem all it usually takes is one search on the internet to get the answers you are looking for.
Q. Can you throw some light on how did you and your team manage the time and coordinate during the onsite finals? It would be great if you could share some tips for the next year ICPC aspirants.
A. Try and identify the cakewalk + easy problems as quickly as possible and get rid of them. After that the pace of the contest slows down considerably and you can decide how your team wants to manage the keyboard etc. depending on the contest.
Q. What did you do to improve over these years and maintain your target status for all these years with all the competition? What do you think was your most effective method to improve? Any hacks on how to reach where you are in less time ?
A. The most improvement usually happens when you are having too much fun to notice it. So, as long as you are enjoying practicing, carry on.
“It was fun, and that was enough motivation for me to get started” and that is what should be the ultimate motivation. So, kids if you are preparing for any programming competition, or have just embarked on the journey into the programming world, make sure you enjoy the ride. It will be all worthwhile in the end.
That will be it for our series of interviews with the ACM ICPC 2016 – 2017 world finalists. We hope you enjoyed them and we hope they have inspired you enough to pursue your programming interests. In anticipation of covering some more of you in the years to come, we will not put down the pen. If you liked these interviews and would like to hear from some more famous programmers, kindly do let us know and we shall bring them all for you.

Greetings CodeCheffer! We are back with yet another stronglyConected programmer, Anuj Yadav. A member of team “stronglyConnected” from Birla Institute of Technology & Science – Pilani Campus Anuj takes us through his journey to the ACM ICPC 2016 – 2017 World finals. So, fasten your seatbelts and enjoy the ride.
Q. How old were you when you started programming and what got you started in programming?
A. I started programming in the second semester of my college. I saw my college friends doing questions on SPOJ in their rooms and decided to try it out myself.
Q. How to start preparing for ACM ICPC for those who are new to algorithms and competitive programming? It would be great if you could share your journey from a beginner to a World Finalist today.
A. I think the best resources to start preparing ACM ICPC for a beginner is to start doing questions on CodeChef, Codeforces, Topcoder or Hackerrank starting from the easy problems on those sites. They cover a wide range of topics and have editorials for most of the problems so that you won’t get stuck. You should also do questions on Project Euler to improve your mathematics. Start taking part in CodeChef, CF, TC, HR contests after you have reached a basic level of coding. Make sure you up solve the problems that you could not solve during the contests.
I started by doing 100 SPOJ problems and after that I started doing CodeChef Contests, Codeforces Contests, Topcoder SRMs and some Hackerrank Ad-Infinitums. CodeChef contests are very good for learning new data structures. Nowadays, I only do TC SRMs and CF contests.
Q. Can you throw some light on how did you and your team manage the time and coordinate during the onsite finals? It would be great if you could share some tips for the next year ICPC aspirants.
A. Each problem was read by at least two of the members of the team. If one of the members has a solution for the problem in mind then he explained the problem to the other person who verified the solution. If the solution was agreed upon by the two people then one of the people would code the solution (Usually Pranet or Akul in my team) and the other person would move on to read other problems.
We prepared for the regionals by doing many virtual gym contests on Codeforces. It is important to ensure that you practice team contests in an environment that would be there at the regionals. As there is only one computer available for coding during the regionals you should also ensure that you use only one computer for coding during your team practice.
Q. Do you have any other thoughts as we wrap up?
A. Please do not get into the habit of solving only easy problems rather than the ones that challenge you as that habit is tough to break later.
Good Tips for improving:
We will be back many more wonderful thoughts from these programming geniuses in our future posts. So, keep watching this space. Till then, share this interview among your friends, and family and send in your wishes and questions for them. #GoForGold.
