    I haven't used HackerRank yet, but Codewars is the most similar to LeetCode in terms of having a large library of problems you can solve in multiple different languages. It's a lot more focused on being crowd-sourced though so it has a larger library and the solutions aren't paywalled like in LeetCode

    A little more mathy. Instead of submitting a bit of code you actually submit the answer to a problem that should be solved through code. But it's free and unpaywalled so it's a cool little project. Currently around 760 problems

    There is a mathematical focus and has good examples of why some problems need optimized algorithms. You get exposed to a lot of cool math concepts and are challenged to write in efficient time and space complexity.
