CodeChef: A Platform for Aspiring Programmers
CodeChef was created as a platform to help programmers make it big in the world of algorithms, computer programming and programming contests. At CodeChef, we work hard to revive the geek in you by hosting a programming contest at the start of the month and another smaller programming challenge in the middle of the month.
About CodeChef February Long Challenge:
CodeChef Long Challenge is a 10 day monthly coding contest where you can show off your computer programming skills. The significance being- it gives you enough time to think about a problem, try different ways of attacking the problem, read the concepts etc. If you're usually slow at solving problems and have ample time in hand, this is ideal for you. There would a tremendous amount of learning while competing. We also put in a lot of efforts in getting quality problems, which would in turn foster your learning while solving them.
Duration: 10 Days, From 3rd February 15:00 hrs IST to 13th February 15:00 hrs IST. Check your timezone here.
Eligibility Criteria: Anyone with a knack for Programming :P
Our contests are open to all the programmers across the globe. However, all the participants are expected to abide to CodeChef Code Of Conduct.
What is it for you?
The idea behind these programming contests is that we want you to learn while competing. Also we believe that it is alright to refer to tutorials, books and other materials, learn a concept and then apply the same to solve a problem during a contest. But it is not alright to copy other people's solutions or seek other people's help to solve a problem without understanding it. The dividing line may seem to be thin but it can be captured by the spirit of learning. If whatever you are doing is making you learn while you do so, we tend to believe that it is alright.
Not just that, as a token of motivation we also give away cash prizes and goodies to the winners of the contest. However, our sole intention lies in making our users learn new concepts while competing. FYI, here are the list of prizes:
- 1st prize: INR 12000/-
- 2nd prize: INR 8000/-
- 1st prize: $400
- 2nd prize: $300
