Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/aditeyabaral/hashmap-lemmatizer

A simple lemmatizer made as a part of the Data Structures (UE18CS202) course at PES University. We used the concepts of graph networks combined with a HashMap to create the database of words along with their lemma.
