What do you do when you cant do most of the remaining problems ?

I am very rusty on my leetcode since I didnt have any interview in the last 5 years (because I didnt change jobs).

So I can do some leetcode easy ones. But it seems like i am running more and more into questions that I cant solve. Which means I have to look at the solution. If I had a goal of 2 problems a day in the past now I cant achieve that goal since I cant implement the problem that I just saw the solution to.

So nowadays I am just checking problems and realizing I cant solve them. Checking the solution and leaving it for a future date. See more problems and I cant solve them. Leave them too for a later date. In the end i solved 0 problems today
