Data Structures And Algorithms

This repository consists of Beginner to Intermediate level Data structures and Algorithms problems with solutions solved in Javascript language.

Common setup

• Install nodejs
• Open terminal and type --version or --v to make sure node is installed successfully
• Download zip file and unzip folder
• Open project in your favorite IDE
• Open terminal type the node filename click enter to execute the problem. Ex: node array-strings/reverse-string.js

Explanation on Data structures and algorithms

Data structures

A data structure is a particular way of organising data in a computer so that it can be used effectively and to be processed in an efficient time and space.

Types of Data structures

Data structures can be divided into two categories, they are as follows:

1. Primitive data structures: Primitive data is not an object and has no methods. There are 7 primitive data types in Javascript:

• Number
• String
• Boolean
• Undefined
• Null
• Bigint
• Symbol

2. Non-primitive data structures: This is further divided as follows:

• Physical Data structures: Arrays, Linkedlist
• Logical Data structures: Graphs, Tree, Hashing, Stack, Queue, etc

Algorithms

An Algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output.

List of Algorithms

1. Greedy Algorithm
2. Divide and Conquer
3. Dynamic programming
