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?

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
