D、堆一定是完全二叉树。A heap must be a complete binary tree. E、最小堆中,某个结点左子树中最大的结点可能比右子树中最小的结点小。In a minimum heap, the largest value on some node's left child tree could be possibly smaller than the smallest value of its right child tree. ...
One thing for sure is that all the keys along any path from the root to a leaf in a max/min heap must be in non-increasing/non-decreasing order. Your job is to check every path in a given complete binary tree, in order to tell if it is a heap or not. Input Specification: Each...

Heap is not necessarily a complete binary tree 暂无答案
Which algorithms can be used on linked lists? Which on arrays? Which of both? I wouldn't recommend sorting a linked list, but merge sort is doable. Merge Sort For Linked List For heapsort, see the Heap data structure above. Heap sort is great, but not stable Sedgewick - Mergesort ...

A max-heap is a complete binary tree in which the value in each internal node is greater than or equal to the values in the children of that node. Explanation: Heap before inserting ‘35’: After inserting ‘35’ will swap with ‘15’ and then with ‘30’. New array order ...
A1064 Complete Binary Search Tree (30 分| 二叉查找树,附详细注释,逻辑分析),写在前面思路分析给你1个序列,所有的数都非负且不同,用这个序列建一个完全二叉搜索树,再给出这个树的层序序列解题思路知识,参考代码易理解...
Heap Sort example A heap is a binary tree whose structure ensures two properties: Shape property A leaf node at depth k > 0 can exist only if all 2k−1 nodes at depth k − 1 exist. Additionally, nodes at a partially filled level must be added “from left to right.” The root ...
and each element of the binary heap is stored into A[1…H] respectively. The root of the tree is A[1], and given the index i of a node, the indices of its parent parent(i), left child left(i), right child right(i) can be computed simply by ⌊i/2⌋, 2×i and 2×i+...
