What is the time complexity of Selection Sort?

O(n²) worst, average, best—unyielding quadratic grind.

Selection Sort vs Bubble Sort: which is faster?

Selection wins swaps (O(n) vs O(n²)), but both crawl large arrays. Pick by memory writes.

When should I use Selection Sort?

Tiny arrays (<50), education, or swap-expensive storage. Otherwise, library sorts.

Selection Sort: Brutal Simplicity in a Quick-Sort World

Q: When should I use Selection Sort?

Tiny arrays (<50), education, or swap-expensive storage. Otherwise, library sorts.

Imagine lining up kids by height, picking the shortest each time. That's Selection Sort—simple, swap-happy, and a gateway to algorithm mastery. But does it belong in real code?

⚡ Key Takeaways

Selection Sort is O(n²) time, O(1) space—simple but slow. 𝕏
Fewer swaps than rivals make it swap-thrifty for special cases. 𝕏
Ideal for learning and tiny data; grounds AI-era coders in basics. 𝕏
