Linked List: Frequently used Operations

🔥 Interview Questions with Beginner Friendly Explanations and Pseudo Code 🔥

👇

0️⃣ Basics

✪ What is a Linked List?

• a LINEAR data structure
• its elements may not be in contiguous memory location
• each element has a reference to its next element

✪ What is an element in a Linked List popularly called?
A Node.

++

✪ What is the structure of a Node in Linked List?

A node has 2 parts.

• First one contains the value
• Second one contains the reference (or, pointer) to the next node. For the last node this is NULL as it doesn't point to any other node.

Tree, Binary Tree and Binary Search Tree

Know the difference. 👇

0️⃣ Introduction to a Tree

✪ A Tree is a data structure where each element is called as a "Node".

✪ Unlike a Linked List, a Node in a Tree can point many (child) nodes.

✪ The first node from which traversal begins is called the Root Node.

++

✪ Each child node can be root of a separate tree. Each such trees are known as "Subtrees" of a given node.

✪ The number of parents, a node can have is called its "In-Degree" and it is always 1.

✪ The number of children, a node can have is called its "Out-Degree".

1️⃣ Introduction

An array is a "collection of items" stored at contiguous memory locations.

Syntax: All items are written comma-separated inside square brackets.

Example: [1, 2, 3, 4, 5]

There are total 5 items in the array. 1 is the first item, 2 is the 2nd and 5 is the last.
