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.

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.
