Hit 100 LeetCode problems, still can't do a basic string question alone

I passed problem 100 last night on LeetCode. Thought I'd feel like I earned something. Nope. Today I tried a simple reverse words in a string problem and froze for 20 minutes. My code worked but I needed to peek at the solution for the split and join logic. It made me wonder if grinding numbers means anything. Has anyone else hit a big count and still felt stuck on basics? How did you break past that wall?

Counting problems isn't the same as knowing the patterns. Peeking at split and join just means you haven't drilled that specific move enough, not that the hundred problems were worthless.
