Introduction to Data Structures

Data structures are ways to store and organize data in a computer. They range from simple variables and arrays to complex structures like segment trees and balanced trees.

Program execution is inseparable from data structures. Different data structures have their own strengths and weaknesses, and are suited for different types of problems. Selecting the appropriate data structure for a specific problem can greatly enhance a program's efficiency. Therefore, it is essential to learn a variety of data structures.
