In today’s DSA tutorial, I explained Insertion Sort from scratch with a complete Java implementation.
Each step of the algorithm is broken down so you understand how and why insertion sort works.

In this video, you will learn:
What Insertion Sort is and why it works so well on small datasets
Complete Insertion Sort implementation in Java
Step-by-step workflow of the algorithm
Line-by-line explanation of the Java code
How shifting and insertion actually happen (with diagrams)
Best, Average, and Worst Case Time Complexity
When and where Insertion Sort should be used
Why Insertion Sort is faster than Bubble & Selection Sort on nearly sorted data

This video builds strong sorting fundamentals and helps you clearly differentiate between Bubble, Selection, and Insertion Sort.

Perfect for:
* DSA beginners
* Java students
* Coding interview preparation
* University exams & lab assignments
