This was also the birth of the heap, presented already by Williams as a useful data structure in its own right.[3]In the same year,Robert W. Floydpublished an improved version that could sort an array in-place, continuing his earlier research into thetreesortalgorithm.[3] 堆(Heap) 堆是...

#1) Heap Sort algorithm to sort in ascending order: Create a max heap for the given array to be sorted. Delete the root (maximum value in the input array) and move it to the sorted array. Place the last element in the array at the root. ...

The heapsort algorithm can be divided into two parts. In the first step aheap is built out of the data (seeBinary heap § Building a heap). The heap is often placed in an array with the layout of a completebinary tree. ...
