Data Structures and Algorithms

Some basic implementations of important data structures and algorithms in Java, along with a few LeetCode questions. I'll keep on adding more solutions of LeetCode problems and if you want, you can add them too!
Also, I've started adding solutions to AlgoExpert problems. You can find them in the Contents section.

Built With

  • Java 11 - Since all the data structures and algorithms are implemented with Java, so there's nothing else to be setup except that.

Getting Started

To get a local copy up and running follow these simple steps.


You need to have Java 11 setup in your local machine before you can run any one of the programs. Check out the official guide from Oracle for that.
