problems are quite interesting (after initial days, those are usually trivial)

e.g. once in 2017 you had problem1: implement an interpreter for this asm-like language. ok, 5 instructions, super easy. ...problem2, run this asm-like program. You couldn't, it was 10^n iterations, would take days. You had to read, understand and optimize the asm-like code.

last year I was amazed writing a function to check if two rectangles intersect (you can do it in like 2 lines)

so, TLDR, you get a lot of "hey that's cool! I never thought about it"
