A collection of problems, concepts, and explorations I’ve practiced while learning Haskell. This repository serves as a personal journey through functional programming, with examples ranging from beginner concepts to more advanced functional patterns.

This repo contains:

• ✅ Solved problems – coding challenges implemented in Haskell.
• ✅ Concept explorations – experiments with Haskell’s core concepts like recursion, higher-order functions, type classes, monads, etc.
• ✅ Notes & references – explanations and takeaways for quick revision.

Whether you’re just starting out with Haskell or revisiting functional programming fundamentals, you might find these snippets useful.

│── README.md         # You are here

Make sure you have GHC (Glasgow Haskell Compiler) or GHCup installed:

ghc --version

You can install via GHCup:

curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh

To compile and run a file:

ghc filename.hs -o output
./output

Or run directly with runghc:

runghc filename.hs

Some of the Haskell concepts I’ve explored here include:

• Functions & Recursion
• Higher-Order Functions
• Pattern Matching & Guards
• List Comprehensions
• Type Classes & Instances
• Functors, Applicatives, and Monads
• IO in Haskell
• Problem-solving with a functional mindset

• Strengthen my functional programming skills
• Build a solid foundation in Haskell
• Document my learning journey

This repo is mainly for my personal practice, but if you spot improvements or want to add new problems/concepts, feel free to open a pull request or issue.
