An ebook to get started with Data Structures. It contains handwritten notes to get a basic idea of Data Structures like Array, Linked Lists, Stack, Queue, and Trees.
I have also included the method to convert an infix expression to a prefix, a prefix to an infix, and a postfix to an infix.
In the trees section, I have tried to cover the basic types of trees like a binary tree, strict binary tree, full binary tree, complete binary tree, BST, and AVL trees along with tree traversal methods.
I also covered B Tree & B+ trees along with binary heaps and a short introduction to Hashing.
It is a 30 Page Short PDF to get you started with Data Structures.
