Answer 1

You are doing it correctly the first time, it works on windows.
The problem is that sololearn runs on linux and clock() doesn't play nice there for some reason.
It seems to always return 0, even on the linux build I have.

Check out https://linux.die.net/man/3/clock_gettime for linux instead.
Maybe https://en.cppreference.com/w/cpp/chrono

I'm not too experienced in linux so I can't really go deeper, sorry. :(

Answer 2

Little edit: seems sololearn doesn't run on linux, appearently.
I still recommend that you use chrono though. :)
