#70 Selection Sort Explained in 60s! 🔍 | Day 3: 15-Day DSA Challenge #java #shorts #ytshorts

Day 3 of our DSA series! 🚀 Today we’re mastering Selection Sort.

​Stop "bubbling" and start "selecting." We break down the dry run for [5, 3, 1, 8, 2] using simple search logic:

🔍 The Search: Scan the unsorted part for the smallest number.

🔄 The Swap: Move the minimum to the front (Only 1 swap per pass!).

✅ The Lock: Secure the position and repeat.

​Senior Engineer Insight:

Selection Sort is unique because it minimizes write operations. While Bubble Sort swaps constantly, Selection Sort only performs O(n) swaps, making it useful when memory writes are expensive!

​⏳ Complexity: Always O(n^2) (Best, Average, and Worst).

⚖️ Stability: Unstable (Find out why in the video!).

​Tomorrow: Insertion Sort—sorting like a deck of cards! 🃏
