在本篇文章中,我们主要介绍functionclass的内容,自我感觉有个不错的建议和大家分享下
struct TreeNode { int val; TreeNode *left; TreeNode *right; TreeNode(int x) : val(x), left(NULL), right(NULL) {} }; class Solution { //record all the path, though dfs is not time efficient bu also work at most time public: void DFS(TreeNode* root, int curSum, vector<int> curPath, vector<vector<int>>& ansPath, int sum) { if(!root) return; curSum += root->val; curPath.push_back(root->val); if(!root->left && !root->right) { if(curSum == sum) ansPath.push_back(curPath); return; } DFS(root->left, curSum, curPath, ansPath, sum); DFS(root->right, curSum, curPath, ansPath, sum); } vector<vector<int> > pathSum(TreeNode *root, int sum) { // Start typing your C/C++ solution below // DO NOT write int main() function vector<vector<int> > ansPath; vector<int> curPath; DFS(root, 0, curPath, ansPath, sum); return ansPath; } };
文章结束给大家分享下程序员的一些笑话语录: 手机终究会变成PC,所以ip会比wm更加畅销,但是有一天手机强大到一定程度了就会发现只有wm的支持才能完美享受。就好比树和草,草长得再高也是草,时间到了条件成熟了树就会窜天高了。www.ishuo.cn
