In problem “Back to School 1”, i fell disappointment when i submit it 5 mins of beginning of the contest but get WA after stuck at that i see suddenly the op format changed, and i already got a piles of WA and that leads me to left the contest when i see that there is no rejudgement.So disappointment for me today,btw first problem is little bit tricky(nice) :P.


@humble_rookie this solution is O(m*(n-m)) and this got an AC while if we take the worst case it will be O(n^2/4) ~ O(n^2) and with 10^5 it shouldn’t work but it did?? Why you guys made weak test case specially in the 3rd question??
Back to school 1 itself didn’t have correct output format so that’s a wrong question too.
I liked the first question but overall contest wasn’t satisfactory.
