As we can build a heap from an array without requiring extra memory (for the nodes, for example), heapsort can be used to sort an array in-place. Source: Internet
Introsort is an alternative to heapsort that combines quicksort and heapsort to retain advantages of both: worst case speed of heapsort and average speed of quicksort. Source: Internet
Comparison with other sort algorithms Although heapsort has the same time bounds as merge sort, it requires only Θ(1) auxiliary space instead of merge sort's Θ(n). Source: Internet
If using efficient sorting such as mergesort or heapsort this is an (n log n) average and worst-case algorithm. Source: Internet
LSD radix sorts have resurfaced as an alternative to high performance comparison-based sorting algorithms (like heapsort and mergesort ) that require O(n · log n) comparisons, where n is the number of items to be sorted. Source: Internet
Overview The heapsort algorithm can be divided into two parts. Source: Internet
