Hello codeforces, ↵
↵
Recently I was practicing 1800 rated problems and I came across this [latter picking](https://codeforces.net/contest/1728/problem/D) problem. I implemented O(n ** 2) solution and submitted in pypy. here is the link to the submission ([pypy submission](https://codeforces.net/contest/1728/submission/262363309)) But it got tle at test 5. I was very confused why this is happening as the n for this problem is 2000. ↵
↵
I changed the interpreter to python 3 and submitted the solution and it gets passed.↵
↵
Can anybody tell me what is the potential problems here? ↵
↵
here is the python3 submission ([python 3 submission](https://codeforces.net/contest/1728/submission/262363070)).↵
↵
both submissions are identical but I got tle on pypy submission.
