Sort before insert — A small, yet powerful extension to Merge sort tree

Revision en1, by darkkcyan, 2020-12-12 09:45:32

Hello Codeforces!

Today I wanted to gain contributions share my small invention during my upsolving. I don't know if there existed a similar idea yet, but as far as I can tell, the editorial for the problem does not use my idea. I think it would be nice to share with you guys and have your opinions on this idea.

Idea explanation

Tags #segment tree, #merge sort tree
