On January 10th 2010, we at CodeChef witnessed the most awesome teams from campuses all over India battle it out in person at the Mumbai headquarters of Directi. 639 teams of three each, had registered for the CodeChef Campus SnackDown, a two round ACM ICPC styled coding contest. The first round of the SnackDown took place on 21st November 2009. We then flew the top 7 teams from various corners of India to prove their mettle.
The 21 finalists met on 9th January for a pre-event dinner on the night before the contest finals. Here they got a chance to interact with each other, meet Bhavin (CEO of Directi) and mingle with other personnel from Directi.
Good food, interesting conversations and some fun laughs turned the dinner into a fun filled night!
The next morning at 9:30 AM teams met at the DirectiPlex with more food, some table tennis and of course, a 4 hour final on site round of the SnackDown to look forward to!
And now finally, after multiple rounds, tiresome travel and sleepless nights, we present to you the CodeChef Campus SnackDown Winners!
Bhavin and Amit with Yash Kumar (18yrs), Nadeem Moidu (20yrs), and Kunal Jain (19yrs)
Dream is an example of national integration; hailing from Rajasthan, Kerala and Chhattisgarh, these three young programmers met at IIIT Hyderabad. Inspired by their Seniors – The Kings Gambit, they formed their own team - Dream and went on to win the SnackDown!
Ramki and Bhavin with Purav Shah (20yrs), Pratik Tandel (20yrs), Krunal Manik (20yrs)
This team’s friendship goes back to school days. Having started programming in the first year of engineering, they were introduced to algorithms and contests by their friend and mentor Varun Jalan (most of you know him as syco). Under Varun’s guidance team Phoenix was formed and they are soon going to represent India at the ACM ICPC world finals in China.
Bhavin and Yazhini with Akhil Ravidas (20yrs), Abhilash R (20yrs) and Venkatesh Basker (19yrs)
Counter Gambit is formed of three hardcore Southies. Since each of them are from completely different programming backgrounds they have their our own strengths and weaknesses. However, as a team, they are really quick in solving problems which helps them get a head start in most contests, or so they’d like to think
They too are representing India at the ACM ICPC world finals this year.
The rest of our finalists are (in order of ranking):
Team: TheKingsGambit
Institution: IIIT - Hyderabad
Team Members: Anshuman Singh (21yrs), Gaurav Agarwal (22yrs) and Rajat Goel (21yrs)
Team: BruteForce
Institution: IIITM - GwaliorTeam Members: Shilp Gupta (22yrs) Manyata Goyal (21yrs) and Vineet Chaudhary(22yrs)
Team: CKrackers
Institution: Madras Institute of Technology
Team Members: Rajesh Venkatachalam (20yrs) Rajesh Rajagopalan (20yrs) Gokulakrishnan Gopalakrishnan (20yrs)
Team: DareToCode
Institution: IIIT - Allahabad
Team Members: Imran Khan (22yrs) Surendra Kumar Meena (21yrs) and Tasnim Khan (20yrs)
We had a lot of fun with the CodeChef Campus SnackDown and would love to do something like this again. We also have some fun interviews with the rest of these teams so let us know if you want more insiders information.
Cheers,
Team CodeChef
Hey Guys,
From the 14th to the 21st of December ‘09 we had the Facebook CodeChef ‘Comment to Win’ contest. Each day we uploaded a photograph of a different CodeChef merchandise that we would give away. Participants were then asked to comment on the photograph. Every 24 hours we had a lucky draw and 5 people from among all that had commented were selected to receive the merchandise of the day. Hemant Verma was the luck winner of an iPod Touch, our merchandise for the final day!
We had a lot of fun with this contest and we hope you like the photographs we put up. The comments received were just awesome and the enthusiasm you guys showed is really appreciated!
I’m sure you’re all wondering who the man in all the photographs is. That’s Pranab Kelkar, just another friendly DirectIan who agreed to be our model for the contest. Thanks a lot buddy!
While a lot of the comments deserve a mention, here is our favourite comment for each photograph.
Day 1 Winners: Vikesh Khanna , Abhishek Kona , James Olabode Samuel , Shiv Prakash , Dezul Udani

Day 4 Winners : Pradeep Nayak , Kushagra Gour , Rajat Kansal , Vimalkumar Jeyakumar , Jayakrishnan Nair

Favourite Comment : Ankush Gupta
A famous saying goes like,that “Books are the man’s best friends”. Certainly that’s very true and evident from the pic
The power in the written word (speciallty algorithms!) is so immense that it makes the chef sleepy most of the time. Mark Twain has rightly said : Good friends, good books and a sleepy conscience: this is the ideal life.
Our winner of the iPod Touch for Day 5 of the contest : Hemant Verma
Favourite Comment : Abhi Arya Bhat
boy: (serious) i love you.

ChocoBananas,
In our previous 10 day algorithm challenges we’ve offered prizes to the top 5 participants from India and the top 5 participants from the US. We’ve seen a lot of participation from international participants and are now deciding to expand our prizes to this set of awesome folks . Starting in the December contest, everyone is eligible for prizes: the top 5 users in India and the top 5 users globally.
Enjoy,
Amit
Snackdowners,
We understand that there were some problems with the contest this weekend. For those who missed it:
We’ve evaluated all the options and here’s what we are going to do (brace yourself)… Re-Snackdown: Sunday December 20th 4-7pm - only teams who solved at least 1 problem in the original Snackdown are eligible for the finals/prize money. Some of you are screaming at your monitors (especially those in the current top 5)…this isn’t fair… we hear you but there is no way to make everyone happy. We screwed up, we’re sorry. Here’s the other options and an explanation of why we are taking this approach:
Some people will undoubtably feel like we should’ve taken one of the approaches listed above (especially those in the original top 5). We’re sorry, don’t hate us… feel free to comment and let us know what you think… try to be nice.
Amit
Hello,
Since the CodeChef Snackdown is the first time we are holding a team based competition, we wanted to make sure that everyone is comfortable with the new team based format and also that everything is working fine on our end. Because of this, we have planned a practice run this Thursday, 19th November from 20:00 IST to 22:00 IST. The rules and format are the same as the Snackdown.
You need to visit the contest landing page and click on the registration link provided at the bottom of the page. You will have to register a new team with a unique team name, but your team display name can be the same as the one for the main contest. On the day of the practice run, you can login using the credentials of your team account for the practice run and you will be able to view problems and submit. Bon Appétit!
Regards,
Aniruddha
