Answer 1

Ash no clue, sorry. I am not a big wizard in CPP and this code contains some fancy I/O handling I am not familiar with. Might as well be because of how the Sololearn engine runs and compiles the code.

On another note, this looks VERY fishy to me. Redefining a built-in data type. I am sure this would blow the fuse in a professional codebase.

#define int long long

it messes with the return type of main method as well, breaking convention.
