YouTube Video Editorials for Every(Almost) Contest (Round #643 updated)

Revision en12, by striver_79, 2020-05-18 10:30:12

I have been uploading video editorials(B, C and D mostly) for Div-2 and Div-3 rounds. The videos are generally updated within 5/6 hours after the contest ends. This blog will contain all the video links. It will be updated after every contest gets over and the videos are uploaded.

Educational Round:

  • Problem DLink (N log^2 Approach) (Binary Search + Fenwick Trees)

  • Problem DLink (N log N Approach) (Binary Lifting on Fenwick Trees)

Round 643:

Round 642:

Round 641:

Round 638:

Educational Round #86:

Round #637:

Round #636:

Round #635:

Round #633:

If you feel I can improve in any aspect, please drop in your valuable advice below. Please do-not expect me to make editorials on Div2-E or above because I solve it sometime during the contest hours due to the time constraint.

P.S: I never posted this, because I doubted on myself whether I could do it for long or not, on whether people will understand the explanations or not.
