# Data Structures and Algorithms

This repository is my self study guide for data structures and algorithms. I implement them from scratch in Kotlin
and then write unit test for them.

What better way to learn a language and new concepts exists other than practicing them.

## Data Structures

* Linked List [Implementation](https://github.com/dnutiu/dsa/blob/master/src/main/kotlin/data_structures/linked_list/LinkedList.kt) | [Tests](https://github.com/dnutiu/dsa/blob/master/src/test/kotlin/data_structures/linked_list/LinkedListTest.kt)

## Ranking

* BM25+ [Implementation](https://github.com/dnutiu/dsa/blob/master/src/main/kotlin/ranking/bm25/Bm25Plus.kt) | [Tests](https://github.com/dnutiu/dsa/blob/master/src/test/kotlin/ranking/bm25/BM25PlusTest.kt)
