Hey Leetcode community,

I've been doing leetcode for ~3 months now and have done 357(111 Easy | 213 Medium | 33 Hard) problems and I find myself in a situation where it's hard to improve upon.

For example, I feel like I can do pretty well on some type of problems (Tree DFS| BFS, Graph DFS| BFS.....), but there are also problems that I still can not solve by myself no matter how hard I try, how hard I study the patterns and concepts (like some dynamic programming/ backtracking problems). I just don't feel confident at all for my upcoming coding interview, like I know there will always be problems that I do not know how to solve even with hints.

How do you all study and overcome this bottle neck period?

Thanks
