Solving LeetCode Problems in Haskell & Rust

In 2025, we did a long blog series where we solved LeetCode problems using both Haskell and Rust. This allowed us to compare how various data structures and problem solving constructs work in a functional language like Haskell versus a more imperative language like Rust.

For a deeper understanding of the skills behind problem solving in Haskell, you should sign up for our Solve.hs course. This course starts by helping you solidify your basic knowledge of lists and loops. Then you'll learn about all the important data structures and how they're a bit different in Haskell. You'll also learn how to write critical algorithms in Haskell, particularly for graph problems.
