I submitted a fairly easy question with N(log(N)) complexity and N<=10^5 which as per theory should pass all test case with a time limit of 1sec. I got TLE in PyPy3 which supposedly runs faster ("Almost always, if you send a solution on PyPy, it works much faster") but the same solution got accepted in Python3.

Can someone please explain the logic and reason behind the same?
