This repository is for anyone and everyone who wishes to understand what are data structures and how algorithms work. This repo is specially for computer science and information technology students. This repo includes – 1. Theory & algorithms - Understand the working of data structures and algorithms that operate on them. 2. Practical Implementation (Programs) – Implement the DS and algorithms in the form of computer programs using C++ programming language. We will be covering many topics in DS such as - What is Data structures, why do we need DS, Algorithms, Algorithm analysis, time and space complexity, types of Data structures - linear and non linear types, stack, queues, linked list, graphs, trees. Algorithms - Sorting, searching, tree traversal etc.
