Our 66th Lunchtime took place on November 24 and it was a showdown to remember with a major rank list shake-up! Keep reading to read who gained ratings and who lost them in the November Lunchtime.
Leading the pack in Div 1 was uwi, who is presently ranked number 1 in Japan and number 5 globally. Following our 100th Cook-Off, we mentioned in our Contest Recap that uwi was less than a hundred rating points short of a spot in the global top 5. Looks like, uwi took up the challenge and dethroned China’s ACRush to claim the world number 5 spot. But ACRush is a regular in our Long Challenges, stay tuned to see if he makes a comeback next month.
Other notable mentions in Div 1 are zemen from Russia who moved to 5-star status in this competition and rns5 from North Korea who went from 5 stars to 6. natsugiri, also from Japan, rounded out the top 4, all of whom scored 500. rns5 has risen rapidly through the rating system, gaining a whopping 6 stars since joining CodeChef in August this year. He needs just about 182 rating points to join another, rns4 another celebrated Kim Il-sung University student, in the 7-star club.
In Div 2 mzuev from Russia, took the lead going from 2 to 3 stars in the process. Close behind was xuzijian629 from Japan who was participating in a CodeChef contest for the very first time and made a rating jump of 275 points, which is the maximum jump possible! He promises to be a coder to watch out for. Dubai based antrikshh claimed the third spot, with Indonesia’s sidiqha in 4th place. While no Indians made it to the top 10 in Div 1, 4 Indians secured spots in Div 2’s top 10. A huge shoutout to its_ulure, mindjolt, radon12 and shubham698.
School students were well-represented in the November Lunchtime Div 1 with 9 of them earning places in the top 20. The best performers were tmwilliamlin from Taiwan who was at rank 5, farhod_farmon from Tajikistan at rank 7, and Ukraine’s adalbert at rank 8. Div 2’s best performing school students were its_ulure from India at rank 5, arafat_01 from Kazakhstan at rank 9, and fake_here from China at rank 15.
Special mentions go to female coders amina283 from Azerbaijan and mh755628 from Bangladesh, both of whom made it to the Div 1 top 100. In Div 2, it was hui_yin from Hong Kong and India’s own viralivora who reached the top 100.
Joining xuzijian629 on the list of users who made sizeable rating jumps are mzuev from Russia and tyakennikku from China who improved their rating by 233 points each. Indonesian sidiqha enjoyed a rating jump of 209 points while India’s own its_ulure from West Bengal, increased his rating by 201 points.
The highest participation this month came from India, followed by Bangladesh and Ukraine. India’s National Institute of Technology, Kurukshetra and Jaypee Institute of Information Technology had the most participants in this Lunchtime. If you’d like to spread the word about competitive programming in your school or college, start by creating or joining a CodeChef Campus Chapter today.
Probability (PPAP) emerged as the least solved problem of both Divisions with no successful submissions in Div 2 and just 7 in Div 1. Event (EVENT) was the most solved problem of Div 2 with 769 successful submissions out of a total of 5738 while in Div 1, Beats and Pieces (BPS) got 169 successful submissions from a total of 576. Check out the editorials for this Lunchtime’s problems here.

The November Cook-Off may be behind us, but the excitement still hasn’t left our system! This was CodeChef’s landmark 100th Cook-Off and we rewarded not only our top performers but also a bunch of participants, selected randomly, to show our gratitude. Keep reading to know what went down during this historic Cook-Off.
Over in Div 1, Japan’s number 1 competitive programmer uwi, stole the show by securing the first rank while the second spot went to India’s own rahuldugar. During this Cook-Off IITian rahuldugar increased his rating to 2484, he only needs a few more rating points to join the exclusive 7-star club. We’re rooting for you, Rahul! uwi, meanwhile, has enjoyed top billing in Japan (national rank 1) and a global rank of 8 for a while and only needs around 70 rating points to steal ACRush’s spot in the global top 5. We’ll be waiting to see if he takes up the challenge. (UPDATE: We may have inadvertently predicted a huge rank shift for uwi! Wait for our Lunchtime recap to know more!)
Also in Div 1, artistmusicant and ll931110 who were at ranks 3 and 4 respectively, both graduated to 5 stars during this Cook-Off. artistmusicant was notably the only female programmer in the top 10 during this Cook-Off so hope she inspires all the girl-coders out there!
grikukan from Russia stirred things up in Div 2 where he earned the first rank. This University student is teetering on the brink of Div 1 with a rating of 1786, but he’s had a tumultuous journey through CodeChef’s contests slipping from 6 stars to 3 stars last year, and nobody knows better than us that anything can happen in a CodeChef contest! petergendy4 from the US swooped into second place with a score of 2, and in the process went from 3 stars to 4.
Among school-level coders, sanroylozan from Hungary, evpipis from Greece and adhyyan1252 from India were a cut above the rest. These school students are all 6-star coders, we hope they can all graduate to 7 stars soon and give the more experienced coders some competition.
There were no seismic shifts in this month’s Div 1 and Div 2 order, but 61 users from Div 2 graduated to Div 1 while over double that number (137) fell back to Div 2 from Div 1. Just a reminder that in the word of competitive programming, you can’t get too comfortable with your rating! You have to keep practising and competing to stay on top.
As far as participation goes, India had the most participants with over 2000 coders taking part in the Cook-Off. The United States and Bangladesh were tied in second place with 23 participants each while 9 Cook-Off coders were from Russia.
The problem Truth and Dare, emerged as the most solved problem with 1781 successful submissions out of a total of 4355 while Data Pipelines was the least solved with 0 successful submissions in Div 2. In Div 1 Elephants in a Pond got just 1 successful submission. You can check out editorials for all the Cook-Off problems here.
We conclude this recap with a big thanks to our problem setting panel:
And an extra special thanks to our problem panel admin Hasan Jaddouh (kingofnumbers) who went above and beyond to make our 100th Cook Off memorable for everyone!
The November Long Challenge was an exciting one and we’re reliving all the contest chaos through our official November Challenge Recap.
Our standout coders this month were ACRush (Div 1) and xhm154 (Div 2), both from China who aced the Long Challenge with scores of 800 each. In the Division 2 category, a notable mention goes to browni3141 from the US who made an ambitious leap from 1 star to 3 stars by securing the 2nd spot with a score of 799.199. Div 2’s 3-star coders zhouzhendong and zhouyuyang had snagged early leads, but while they were ousted from the top spots, they each earned a star and moved to the 4-star club. Interestingly, all of the top 10 participants in Div 2 earned at least a star in this contest, so Div 1 regulars had better watch their backs!
Meanwhile, in Division 1, most of the key players in the top 10 retained their existing status with some notable exceptions. samjia2000 from China and wmoise from the USA, both earned the elusive ticket into the red 7-star club. wmoise is now ranked 8th in the USA and 83rd worldwide, while samjia2000 has a country rank of 16 and a global rank of 75. But as we all know, the contests giveth and the contests taketh away! We hope the new entrants are prepared to fight for their spots! We also had North Korean rns5, the lone coder with the purple band, who battled 6 and 7-star competitors to add that coveted 5th star to his band with a score of 799.686.
Shoutout to our top ranking school students whzzt, peehs_moorhsum and samjia2000 who all secured spots in the Div 1 top 10 with scores of 780 and above. In Div 2, 4 of the top 10 ranked coders were students: xhm154, howarli, zhouzhendong and zhouyuyang. These rising stars will soon be keeping experienced coders on their toes!
Our homegrown coders also found themselves in the top 10 in both Div 1 and 2 categories. yash_chandnani from Jaipur retained his 7 stars and secured the 5th spot in the Div 1 rank list with a score of 799.513. In Div 2, halberdier secured the third place while thefear from Uttarakhand and Kolkata’s rv_619 landed the number 9 and 10 spots respectively.
A whopping 7421 coders increased their ratings in the November Challenge, and 301 Div 2 coders graduated to Div 1 with ab_initio from the USA who made a significant 186 point rating jump while India’s very own coder3101 from Jharkhand earned 176 rating points during the Long Challenge. Female programmers from India made their presence in the competition felt with 4 coders making rating jumps of over 200. Mumbai’s ziggywiggy led the pack with a rating increase of 217. Among school students, cunbidun from Vietnam increased his rating by 233 points while ilionoid from Kolkata, India saw a rating increase of 219. The Div 1 pool just got a lot bigger since 307 coders graduated from Div 2 to Div 1 following the contest. Salute to eriktillema from the Netherlands who earned 228 to make this leap.
As for the problems, “Chef and Difficult Contests” ironically emerged as the most solved problem with 9774 successful submissions while Max Digit Tree and Chef and Equations saw just 17 successful submissions each. You can check out editorials for all the Long Challenge problems here.
We conclude this recap with a big thanks to our problem setting panel:

Team CodeChef
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!

Student coders, this is your chance to shine!
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 Amit Upadhyay, a CCDSAP Foundation Level Certificate holder who is placed at Cleartax as a Software Engineer. We asked him about his CCDSAP experience and his tips for aspiring candidates. so read on!
A little background on Amit and his introduction to coding.
Amit completed his engineering from the Army Institute of Technology in Pune in 2018. Amit has always been involved with the world of code. He started coding on the CodeChef platform in his first year, and eventually moved on to making mobile apps in his second year. During this he found that he had a wealth of knowledge (and libraries!) to share with the world, so he began blogging as well. Amit credits the environment in his college for boosting his interest in coding competitively. In his first year, his seniors informed him about the CodeChef platform and he quite enjoyed the thrill of competitive programming.
How did Amit hear about CCDSAP and why did he decide to appear for it?
Amit heard about CCDSAP when Directi landed up in his campus for a recruitment drive. Clearing the CCDSAP also allows one to interview with Directi and Amit decided to make use of this opportunity. Even though his concepts were clear, Amit decided to consolidate his learning before appearing by taking the mock test on the CodeChef website. He recommends taking them to get an idea about the exam format and the correct pacing needed to finish the exam in time.
How should one prepare for CCDSAP?
Amit believes that a strong understanding of the fundamentals of DSA is what is tested at CCDSAP. So how does one get there? He recommends using a good book of DSA theory matched with an equal amount of solving DSA problems, like the ones available on the CodeChef website. He advises that candidates should study one data structure at a time and then solve 10-20 problems based on it before moving to the next. There are also many videos available online to help with the conceptual part. Finally, he recommends the prepare section on the CCDSAP site as an invaluable resource, complete with mock tests.
So where does DSA help one in the industry?
While most products depend on existing frameworks which can be understood by reading the manual, Amit emphasizes that DSA helps you learn how to think. It lets you understand the most optimal way of going about solving a problem, no matter what platform or framework is used. After all, problem-solving skills are universal and carry over to your next assignment as well.
Amit also spoke about how college doesn’t quite prepare you for industry challenges, and a lot of the learning happens on the job. At CodeChef we agree that this is certainly an issue and efforts can be made to bridge the gap between recruiters and candidates. CCDSAP does address this in a small way, and eventually we can bring a systemic change together.
The next CCDSAP exam takes place on the 7th of October. Check this link for details and get in touch if you have any questions for us!
CodeChef has been serving the competitive programming community for a very long time. Today, incidentally on the occasion of our 72nd Independence Day, we make a digression. We are excited to announce that we have something for our developer community too!
All this while, we have seen many enthusiastic CodeCheffers, taking the pain of scraping the CodeChef website and creating various really cool and useful stuff out of it. This has made us go one step further and provide all our beloved developers and programmers with the power to turn their ideas into reality much more easily.
So here we announce the launch of the CodeChef API Hackathon powered by Alibaba Cloud.
What is CodeChef API?
CodeChef API is an OAuth 2.0 HTTP API, which exposes CodeChef resources and data to the developers. You will get to know all the details about the API once the contest starts.
Why?
There are things that we want to do and cannot do on our own. And, there are things that we do not even know and can be done. This is where the awesome community comes in. We have seen numerous enthusiastic users who scrape our website to build stuff that does wonders.
We believe that the API now opens up new opportunities for our fellow developers from the community, and will help them build useful and relevant apps which can help the growing community.
CodeChef API – The internship project
It started way back in 2015, when two of the community members proposed to us an idea of making a CodeChef Android app and we were so convinced that we immediately wanted them to get started. Yes you read that right, an Android app! We will get to that story some other time.
Soon we realised that it would be much better to have an API first and then build the app. Since then, there have been many changes in our priorities and despite being partly ready to launch the API, we couldn’t give it to you.
Now
We thank Alibaba Cloud, who liked our idea of an API for the community and supported us in being able to bring this API to you. It gives us immense pleasure to let you know that via our First Hackathon, we are presenting you a brand new CodeChef API that you can consume and you can also build your apps and deploy them on the Alibaba cloud.
Interns & Internship
We have always been proud of our interns and always try to have them throughout the year. They are the packets of energy and enthusiasm which fuel the overall work ethics of the team. CodeChef API was one such project and we thank all our interns who have contributed to the project in some way or the other – Vikesh Tiwari (aka vicky), Shivam Khandelwal (aka skbly), Prabhat Awasthi (aka hacker_ratty) and Shivangi Gupta (aka shivangi_gupta -_- ). Go, hound them!
And with this, we also extend a chance to grab an internship opportunity to all the users who come up with great ideas and implement them.
Looking forward to it…
Cheers,
Abhijeet
The most awaited flagship global coding competition by CodeChef will unfold the curtains to its onsite round in February next year. After successfully completing its four editions and witnessing participation from over 29K programmers in SnackDown 2017, we can say that SnackDown has come a long way since its inception in 2010.
We have been bombarded with questions by the community who were eagerly wanting to know the dates for SnackDown this year. We are here to put an end to all these speculations. Coming to the answer you’re all looking forward to: the online rounds will kickoff in October 2018 and on-site finals will take place in February 2019. We’ll post the final schedule for SnackDown in September, so watch this space!
Oleg Merkurev of Ural Federal University and Aleksei Daniliuk of NRU Higher School of Economics from Russia raised the trophy of SnackDown and claimed a cash prize of $10,000Till now the final round of SnackDown has been an onsite event hosted in India in the month of June-July. This is also the time of heavy monsoons in major parts of the country. To not let the extreme weather come in our way of hosting a glorious finale on Indian soil we decided to keep it in the month of February of 2019.
