It's been years I am using Codeforces and one thing I always missed was Solution feature on Codeforces.
So, I tried to make one with the intention of helping all the competitive programmers on Codeforces. Now you don't have to wait for days anymore to get solution of contest problems after the contest is over.
What is it? I have made a Chrome Extension, upon adding which, it will place two buttons on every Codeforces problem description page. One "See Solutions" and other "Write Solutions".
This works very seamlessly, do try it. Please do post your solution with full explanation so that others can benefit from it.
Extension: https://chromewebstore.google.com/detail/codeforces-solutions/ojeklbemjjglhffombiogeabanjkofhl
Please do upvote, I am not making money with this Extension. I only want to benefit the community.
