堆积（heap）是树结构的第三种型态。堆积是一棵二元树，其左右子树节点的值均较其父母节点的值小。堆积的根节点值保证是该树最大值。这中堆绩称为最大堆绩。堆积的子树可摆在左边当左子树，也可摆在右边当右子树，因此左右子树俱有相同的性质。-Heap (heap) are the third type of tree structure. Accumulation is a binary tree, its about the value of subtree nodes than those of th

这是介绍的关于三态树方面的源代码,对研究三态树算法有一定帮助。-It is introduced on the tri-state area of the source code tree, the tree algorithm on three-state study has some help.
