Collection of algorithmic coding challenges, I play with in free time. They are primarily sourced from LeetCode, which I solve from time to time for fun and to stay sharp and explore different approaches to simple problem-solving.
This repository serves as a notebook for exploring data structures and algorithms using JavaScript. Problems are organized into folders by category for easy browsing.
The following problem types are currently covered:
- Arrays & Matrices
- Strings & Character Manipulation
- Bit Manipulation
- Sorting
- Binary Search
- Recursion
- Backtracking
- Dynamic Programming
- Trees & Graphs
- Linked Lists
- Stacks & Queues and more...
This is a work-in-progress — I add new problems as I go.
For simplicity sake, all solutions are written in JavaScript (ES6+) and have:
- Descriptions of the problem
- URL to original problem
- Most of them have time and space complexity notes
To run a solution locally:
- Make sure you have Node.js installed
- Clone the repo
- Navigate to a problem folder and run:
node your-solution-file.js
