Hi Codeforces I really want to know 1) (How to jump as fast as possible from newbie range) Skills and Math Needed.

Thank you
Skills:
Middle school level algebra and number theory
Binary Search

Data structures (Map, Set, Queue, Stack, Etc)
DFS/BFS/Etc

I think this is most of it, might be missing one or two though.
Know how to combine aforementioned skills for a single solution and problem solve, and be fast.
