堆排序(HeapSort)是一树形选择排序。堆排序的特点是：在排序过程中，将R[l..n]看成是一棵完全二叉树的顺序存储结构，利用完全二叉树中双亲结点和孩子结点之间的内在关系(参见二叉树的顺序存储结构)，在当前无序区中选择关键字最大(或最小)的记录-Heap Sort (HeapSort) is a tree selection sort. Heap sort is characterized by: the sort process, the R [l.. N] as a complete binary tree structure of the order of storage, using completely binary tree in the parent node and children nodes in the internal relations between relations (see the order of the binary tree memory structure), in the present disordered select keywords maximum (or minimum) record
