When I try to solve a problem a little bit higher above my ability I face a lot of problem. I get stuck then read editorial and solve it later. But what should I do or you would do in this situation:

1. When you can't generate the idea for a specific problem.
2. Then you cant' understand still after reading the editorial.
3. Then you still can't understand solution reading other's code?
4. There's no one you know that you can take help from.
