I was reading through Codeforces blogs when I came across this amazing blog which contained a collection of problems from various topics. I then wrote a script to save all the questions given there in the blog to a CSV file. I successfully completed the script but the attempt was useless as I found out there were 2500 questions from the 100 topics listed there and it seemed better stored in the blog post itself.

Just in case you would like to the use the scrapping script here is the Pastebin link.
