Heap sort is a comparison-based sorting algorithm that uses a binary heap data structure.
Heap sort works by first building a max heap from the input array.
It then repeatedly extracts the maximum element from the heap and rebuilds the heap.
The time complexity of heap sort is O(n log n) and it is an in-place sorting algorithm.
Example: [4, 10, 3, 5, 1] -> [1, 3, 4, 5, 10]
The best sorting algorithm is dependent on the specific use case and data size.
Quick Sort is efficient for large datasets due to its average time complexity of O(n log n)
Merge Sort is stable and has a time complexity of O(n log n) but requires extra space
Insertion Sort is simple and efficient for small datasets with time complexity of O(n^2)
Heap Sort is efficient and has a time complexity of O(n log n) but is not stabl
