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 became quite a bit faster. I am dumbfounded by this phenomenon, and the only explanation that was somewhat reasonable was this (which is crazy to me).

To me, it is crazy that sometimes declaring a bigger datatype can be faster than a smaller one, but I guess this is computer science, and anything can happen.
