Heap Sort

Heap Sort first reorganizes data into a max-heap — a binary tree where every parent is larger than its children — so the biggest value always sits at the root. It then repeatedly pulls the root off, places it at the end of the array, and repairs the heap, until every element is in perfect order. It's an in-place, O(n log n) algorithm used in operating system schedulers, priority queues, and embedded systems where memory is tight.
