Data Structures and Algorithms

The Foundation of Efficient Code:

At its core, efficient code is the result of strategically chosen data structures and algorithms. Data structures provide a way to organize and store data, while algorithms define the step-by-step procedures for solving specific problems. Together, they determine how quickly and effectively a program can perform its tasks.

Understanding Data Structures:

Data structures are like the building blocks of software. Whether it's arrays, linked lists, trees, or graphs, each data structure serves a specific purpose and has its own set of advantages and disadvantages. We delve into the characteristics of some key data structures, examining their use cases and how they impact the performance of algorithms.
