The scoring distribution will be announced closer to the beginning of the round.
The contest finished, contgratulations to the winners:
The participants will be challenged with 7 traditional algorithmic tasks of varying difficulty levels and 1 approximate problem for a duration of 9 days. For traditional algorithmic tasks, you will receive points for every test case your solution passes — so you can get some points with partial solutions as well. For the approximation task, your score depends on the best solution in the contest so far. Here is the detailed timeline of the challenge,
As usual, there will be some nice prizes for the top five competitors:
I am the tester of all the problems. I'd like to thank the problem setters Sanjay Gidwani (sanjaygidwani), Mohd Salik (abx_2109), Orap Andrew (Dalgerok), Saurabh Joshi (Apptica) and Anand Jaisingh (.AJ.).
