Heapsort time

Web22 de jul. de 2024 · Heap sort consists of two key steps, inserting an element and removing the root node. Both steps have the complexity O (log n). Since we repeat both steps n times, the overall sorting complexity is O (n log n). Note, that we didn't mention the cost of array reallocation, but since it's O (n), it doesn't affect the overall complexity. In computer science, heapsort is a comparison-based sorting algorithm. Heapsort can be thought of as an improved selection sort: like selection sort, heapsort divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region by extracting the largest element from it and inserting it into the sorted region. Unlike selection sort, heapsort does not waste time with a linear-time scan of the unsorted region; rather, heap sort maintains the unsorted region in a
