Sorting algorithms don't have to be scary 🧠

Insertion Sort is proof: *Simple Idea. Powerful Results!*

It builds your sorted array one element at a time. Compare, shift, insert. That's it. This visual guide breaks down every single step using `[5, 2, 4, 6, 1, 3]` so you can _see_ how it works.

Save this for DSA prep or your next coding interview! 💾

💡 *What's inside:*
- Step-by-step example with visuals
- Ready-to-use pseudocode
- Time Complexity: Best $O(n)$, Worst $O(n^2)$
- When to actually use it: Small datasets, nearly sorted data, and hybrid algorithms like TimSort

*MASTER THE BASICS. BUILD THE FUTURE.*

🫧 BUBBLE SORT MADE SIMPLE!

Ever wondered how sorting actually works behind the scenes?

Bubble Sort is one of the first algorithms every coder learns. It compares adjacent elements and "bubbles up" the largest values to the end, one pass at a time.

This infographic breaks down:
- How it works step by step
- Full Java implementation with early exit optimization
- Time & space complexity
- When you should actually use it

Perfect for DSA interviews and Java beginners!

👇 Challenge: Try implementing Bubble Sort in Java and drop your code in the comments. Let's debug together!
