LeetCode 111 题,Minimum Depth of Binary Tree 解题思路 1、读题,求解二叉树的最小Depth。 2、用bfs 去解决,队列带上每层的层数。当有一个节点的左右子树都为空时,返回当前层数,就找到解。 Python 代码 # De…
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. 思路: 注意递归传值的方式差异。 算法1: AI检测代码解析 int min = Integer.MAX_VALUE; //此处有bug 不过ac还是没问题的 ...
The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. Note: A leaf is a node with no children. Example: Given binary tree [3,9,20,null,null,15,7], 3 / \ 9 20 ...
