    Why ans[i][j] = ar[i][j-1]? It should be ans[i][j] = ans[i][j-1];

Alright, The problems were so easy, The statement of problem D is written so bad, I just wasted 7 minutes on understanding what it says and finally guessed the statement from the samples, But after all good job.

    Same, even I could not understand it in one go and skipped straight to E. But, it made sense after reading and drawing stuff abit.
    But the contest was overall good for a beginner :D

      Someone wants to create contests, for creating a contest, there should be 2 easy, 2 medium, and 1 hard problem, The person has $$$a$$$ easy problems, $$$b$$$ medium problems, and $$$c$$$ hard ones, He asks you to calculate with this set of problems, how many contests he can make at all.
