data-structures-and-algorithms's Introduction

Data Structures and Algorithms

Introduction

Data structures & Algorithms are an essential part of programming. It comes under the fundamentals of computer science. It gives us the advantage of writing better and efficient code in less time. It is a key topic when it comes to Software Engineering interview questions so as developers, we must have knowledge of Data Structure and Algorithms

Data Structure

In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. Data structure is a way or a format how your data is stored in memory for effecient usage and retrieval.

Algorithms

An algorithm is a set of instructions that are used to accomplish a task, such as finding the largest number in a list, removing all the red cards from a deck of playing cards, sorting a collection of names, figuring out an average movie rating from just your friend's opinion

Algorithms are not limited to computers. They are like a set of step-by-step instructions or an even a recipe, containing things you need, steps to do, the order to do them, conditions to look for, and expected results.
