In a recent Div 3 contest, this D problem https://codeforces.me/contest/2236/problem/D , I solved and submitted my solution in PyPy 3-64, It got TLE ( https://codeforces.me/contest/2236/submission/378497496 ) but same solution I submitted using Python 3 got accepted ( https://codeforces.me/contest/2236/submission/378498806 ). I have faced this issue using python a couple of time also. Can any Python expert help me in this case ?

Thanks
