## Introduction to Data Structure

Data Structure is the representation of the relationship between individual elements of data in the logical sequence. With the help of data structure, you can organize all the data, and you easily under the relation that exists between different individual data.

Data Structures is a concept in which students learn about data, how it is stored, and the way it is processed. An algorithm is used to process the data that is stored. The concept of data structure and algorithms is interrelated and are complementary to each other. When you choose a data structure, it will affect the algorithm that you will choose. If you choose the algorithm first, it will affect the data structure.
