Show HN: DSA Trainer, LeetCode practice with a hint ladder instead of spoilers

https://dsatrainer.com/

Ran 2 monitors for months practicing leetcode. One with ChatGPT up in 'study mode' asking the same questions over and over for ever LC problem, and the other on LC trying to understand what do.

Got tired of the set up and ended up building DSA trainer built around my most common asked questions when I was trying to learn.

Explains the concept in a Q&A type format that guides you to the data structure, explains why it's optimal, shows the brute force method and explains why that won't pass the interview, and has a 5-rung hint ladder, dry run table, and common 'gotchas'.

Pattern pages that explain the foundations and the strengths/weaknesses of each data structure or algorithm and when to reach for them.

Also has Cold Read drills for word-based problems that you can individually or in sessions.

Any feedback would be appreciated!
