key value or index of the child node is always less than (or greater than) its parent node.2. Algorithm description and implementationThe specific algorithm is described as follows: The initial order-to-sort keyword sequence (r1,r2....rn) is constructed into a large top heap, which is the initial unordered area; Swap the top element of the heap r[1] with the last element R[n] to get a new unordered area (R1,R2,......

Heap Sort Heap sorting is a sort of selection using the properties of a heap. Let's discuss the heap first. 1. Heap The heap is actually a completely binary tree, and any one of its non-leaf nodes satisfies the nature: KEY[I] That is, the keyword of any non-leaf node is not greater than or not less than the key word for its left and right child nodes. The heap is divided into large top heaps and small top heaps, satisfying the key[i]>=key[2i+1]key>=key[2i+2] called the large top heap, sati

First, IntroductionHeap sorting (heapsort) is an improved version of the choice of sorting, it can reduce the number of comparisons in the selection of sorting, and thus reduce the sorting time, heap sorting method used to two fork tree technique, it uses the accumulation of trees to complete, accumulation is a special two fork tree, can be divided into Dagen and small Gan.Dagen Required Conditions:It's a completely binary tree.The value of all nodes is greater than or equal to the value of its

Stacking sorting (heapsort) is a sort algorithm designed using the data structure of a stacked tree (heap), which can quickly locate the elements of the specified index using the characteristics of the array. Heap sequencing takes advantage of the maximum (or minimum) keyword of the Dagen (or small Gan) heap top record, making it easy to select the maximum (or minimum) number of keywords in the current unordered region. sorting ideas for heap sorting:The use of large top heap (small top heap) he
