Educational Codeforces Round 16 — F. String Set Queries — Time Limit Exceeded
Hello,
I'm getting time limit exceeded on this problem; 710F - String Set Queries
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?
My solution; 20459110
Thanks in advance!
