Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down ...
要求:此题正好和Maximum Depth of Binary Tree一题是相反的,即寻找二叉树的最小的深度值:从根节点到最近的叶子节点的距离。 结题思路:和找最大距离不同之处在于:找最小距离要注意 l lt r l :r 的区别应用,因为可能存在左右子树为空的情况,此时值就为 ,但显然值是不为 的 只有当二叉树为空才为 ,所以,在这里注意一下即可 代码如下: ...

Easy! 题目描述: 给定一个二叉树,找出其最小深度。 最小深度是从根节点到最近叶子节点的最短路径上的节点数量。 说明: 叶子节点是指没有子节点的节点。 示例: 给定二叉树 [3,9,20,null,null,15,7], 返回它的最小深度 2. 解题思路: 二叉树的经典 ...
