Hi!

Since the editorial will be posted later, I decided to write some quick solutions for the problems I managed to solve, as well as video editorials for C and F.

**A - Little Artem**

**B - Kind Anton**

**C - Eugene and an array**

**D - Challenges in school №41**

**F - Kate and imperfection**

Nice solution for F. Thanks.

Can someone help? this is my solution to B.75967933 I don't understand where I made mistake. I have tried to solve it in less than O(n).
