Hello everyone,

I have started a playlist about a month ago and I have been uploading the tutorials of problems A-D for every Div 2 and A-F for every Div 3 in the playlist starting from Codeforces Round 794. There are over 60 video editorials in the playlist. Hope everyone likes them.

I have suffered almost 4 times out of the last 10 contests. Similar logic getting AC in C++ and TLE in Python, especially for Div 2 D and Div 2 E problems. This is hugely unfair for python coders. I earnestly request the setters and the testers to adjust the constraints and the time limits in such a way that it is almost fair for coders of all languages. Not only did it cost us 1 penalty marking but also sometimes, we don't have enough time to convert the python code to C++.

isn't sortedcontainers not allowed in codeforces?
