As a way to give back to the amazing community, I will make a Youtube channel
explaining algorithm techniques and Codeforces problems solutions.
It will be targated towards newer members who are not very experienced in competitive programming yet.
The problems will be at level Div2 D-E up to Div1 D.

I want to know which method do you prefer ?
1- pick up some old problems that I find interesting and explain the solution and the techniques that I used.
2- pick up a problem from the last contest on Codeforces and explain the solution and the techniques in that problem.
