Can anybody help me in finding the bug in my code for question MCQ games? Link to my code is https://www.codechef.com/viewsolution/19338055 . I have used (a/b)%mod=(a*pow(b,mod2))%mod. @vijju123 answered 26 Jul '18, 19:22

Your code is perfect. But the test files are not. According to the test files, I don't know why, you should print '1' if k is 1. The logically wrong code which fetches an AC: https://www.codechef.com/viewsolution/19346258 Again, it's not your fault, and congrats for solving it.

Thanks for the information @sarthakmanna.

we should print 1 for k=1 because each question has 1 choice...the one person will always tick that 1 option and will always be correct..In short when k=1 there cannot be a wrong answer for any question and hence 1 person is enough to solve all.

According to the question, our task is to "determine the sum of total number of players who has attempted ith question for all (1<=i<=N)". Also, in the explanation section, it is explained as "1st question is attempted by 27 players,second by 9 and third by 3 players.So, the sum of total number of players is(27+9+3)=39. The answer will be 39%(10^9+7) = 39". Similarly, for k = 1, we can explain as, Hope its clear, @swapnil159

I think having a score based ranklist in a long contest makes more sense.
