Minimum Depth of Binary Tree 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 to the nearest leaf node. 这题跟上题几乎一样,区别在于需要求出根节点到最近的叶子节点的深度,我们仍然使用遍历的方式。
LeetCode: Maximum Depth of Binary Tree 题目如下: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 即求二叉树的(最大)深度。
