导读: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. Note:?A leaf is a node with no children. Example: Given binary tree? [3,9,20,nul
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. Note:?A leaf is a node with no children. Example: Given binary tree? return its minimum?depth = 2. ? 求最小的深度,二叉树,这道题目我认为数据是有问题的,所以有176个踩, c++ class Solution { public: int minDepth(TreeNode* root) { if(root==NULL) return 0; int lmin =0; int rmin =0; if(root->left!=NULL) lmin = minDepth(root->left); if(root->right!=NULL) rmin = minDepth(root->right); if(lmin==0) return rmin+1; if(rmin==0) return lmin+1; return min(lmin,rmin)+1; } }; (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
