Hi Codeforces, I was trying to solve this problem, and I was struggling to see why my code TLEs when other people's code (you can search up cses hamming distance solution for this) passes with similar logic.

Turns out when I add #define int long long, my code magically passes and becomes quite a bit faster. I am dumbfounded by this phenomenon, and the only explanation that was somewhat reasonable was this (which is still crazy to me).

I guess sometimes long long really is faster than int.
