力扣leetcode-cn.com/problems/check-completeness-of-a-binary-tree/ 题目要求: 思路:1.利用二叉树节点编号与非空节点的关系来做 思路2:根据完全二叉树的节点分布特点来做。规则在图中 code如下: python class TreeNode: def __init__(self, val=0, left=None, right=None): self.val = val self....
Definition of a complete binary tree fromWikipedia: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 and 2h nodes inclusive at the last level h. Example 1: Input:[...
