Beautiful problems I enjoyed solving
By bgopc, history, 10 months ago, In English

Hello CF community, in this blog post I tried to gather the Questions I've solved and enjoyed them most of them are really teaching and worth spending hours of time on them Hope you enjoy

EDIT: Part 2 added, link

Problems

Note that to solve these problems you need no knowledge except:
9th grade math, a little bit number theory, sorting, elementary dp, elementary bs, set, stack, queue, map

Good luck and hope you enjoy them

EDIT: I added maybe a few problems, I ran out of beautiful problems, unfortunately, maybe suggest in the comments and I'll add them

new ones

Guys a question: do u want me to include recent contests as well?
