Data Structures & Algorithms1

Data Structures are the programmatic way of storing data so that data can be used efficiently. Almost every enterprise application uses various types of data structures in one or the other way. This tutorial will give you a great understanding on the Data Structures needed to understand the complexity of enterprise-level applications and the need of algorithms, and data structures.

We will also be solving lots and lots of questions from websites like LeetCode, CodingBat, and HackerRank to improve our understanding and problem-solving skills.
