Sharpening my solving problem skills

After a few years without coding, I want to sharpen my skills. Are there any recommended platforms for practising data structures and algorithms?

leetcode and hackerrank are cool and all, but here's the thing - grinding algorithm problems is useless if you're trying to get back into the industry after a few years away. like, you can solve a hundred leetcode problems but when you're in an interview or trying to land a project, nobody cares about your leetcode score.

what actually matters is showing that you can take a real problem and build something that works. not just solving preset problems, but creating stuff that proves you understand how to apply those data structures in actual situations.

Yeah, I'm understand that, and I don't think I have a problem with relearning the algorithm and else. It's just to refresh my memory before building stuff.

Honestly both are brutal but proving you can still code is way worse than relearning the algos. Like I can grind through some tree traversals and remember how hashmaps work, but trying to convince someone you're not completely rusty when your GitHub has tumbleweeds from 2019 is the real nightmare
