Hello everyone.

This post is a request to the competitive coding community to improve the current judging system for python and pypy submissions.

I was trying to solve a DP on Trees problem https://mirror.codeforces.com/problemset/problem/919/D here is my solution https://mirror.codeforces.com/contest/919/submission/80857731, Firstly I submitted my solution in Python3 I got Time limit exceeded on test 18 , then I tried to submit it in pypy3 and I got a runtime error on test 32, I figured it out that I was using recursive dfs so I have to increase the recursion limit then I used sys.setrecursionlimit to set recursion limit to 300000 and submitted it again in pypy3 now I am getting a memory limit exceeded on test 6, but I am not getting memory limit exceeded on test 6 in python3 instead I am getting Time limit exceeded on test 18 again. why pypy and python have difference for memory limit??

This is not the first time I am going through this type of problem, many times I have to convert the whole code and submit it in c++, which eventually get executed, are we really not capable to solve this problem.

Why a python programmer has to suffer? My request is to improve the judging system or remove python or similar languages from codeforces patform.

Can some other platforms use the questions of codeforces as one of the question in its practice section? Are there any copyright for the questions?

P.S The user will not be redirected to codeforces to solve the problem.
