Educational Codeforces Round 16 — F. String Set Queries — Time Limit Exceeded

Revision en2, by thecortex, 2016-09-08 16:36:11

Hello,

I'm getting time limit exceeded on this problem; 710F - Операции над множеством строк

Any idea how to tweak my solution to avoid this quadratic runtime in method "count". I reviwed others solutions, and they are all quadratic, but why my implementation is just slower?

The nested for loop gives an asymptotic runtime of O(L^2) where L is input string length.

My solution; 20459110

Any hints would be truly appreciated!

Thanks in advance!
