I am continuously getting TLE on "substring search" (question 1 of step 3 ). I tried declaring global variables, tried passing reference to vectors, reduced function calls but nothing worked. According to me, my code is O(nlogn). Can someone please help me in finding why I am getting TLE. Here is the code: https://mirror.codeforces.com/edu/course/2/lesson/2/3/practice/contest/269118/submission/85793528

Creating (multiple) substr's per check is expensive as it involves allocation and copying of the substring.
The compare function has overloads that take start + length so you can compare the strings without creating a substr.
Finally got accepted. I didn't realize that substr would be that expensive. Thanks a lot.
