Hello Community

I'm wondering what's a good amount of time to stop and look at the solution for thinking of a problem. Usually, I think about a problem for 15-30 minutes before looking at a solution. During that time, I try to solve it naively, and speed it up OR run through a checklist of different techniques to do, Dp, Greedy, etc..

I'm wondering if it is worth it to spend more time, and if it is even possible to solve problems given an infinite amount of time.

Ex. Can a 1200 solve a 2000 hard problem given 5 days? Maybe impossible... maybe not... What is your experience?

Thanks Fluffy-
