Video editorials of Codeforces Round 638 Division 2 (Problems B, C and D)

Many of the starters or intermediate programmers, face a lot of problem in understanding the intuition behind a solution reading the editorial. Keeping this in mind, I have made editorials for today’s Codeforces round.

  1. Problem-B
  2. Problem-C
  3. Problem-D

P.S: I have been making editorials for the last 3/4 contests on a regular basis. (Gets posted on the same night mostly)


Thanks for this. I did A and B in the contest but was confused in C, it really helped me a lot. Thanks brother. Keep making these videos, they are helping noobs like me

Sure @first_semester
