IntroSort Explained 🔥 | Quick Sort + Heap Sort + Insertion Sort

This video explains IntroSort (Introspective Sort) — the hybrid sorting algorithm used in real-world libraries like C++ std::sort.

IntroSort intelligently combines:
Quick Sort for average-case speed
Heap Sort to avoid worst-case O(n²)
Insertion Sort for small partitions

🔹 What you’ll see:
✔ Live recursion depth meter
✔ Automatic switch from Quick → Heap
✔ Small arrays cleaned using Insertion Sort
✔ Pivot-based partitioning visuals

💡 IntroSort guarantees O(n log n) performance while staying extremely fast in practice.

Built using HTML, CSS, JavaScript & Canvas for deep algorithm intuition.
