原题地址 二叉树的层次遍历. 对于每一层,依次把各节点连起来即可. 代码: void connect(TreeLinkNode *root) { if (!root) return; queue<TreeLinkNode *> parents; parents.push(root); while (!parents.empty()) { queue<TreeLinkNode *> children; while (!parents.empty()) { TreeLinkNode *…

leetcode 199. Binary Tree Right Side View 这个题实际上就是把每一行最右侧的树打印出来,所以实际上还是一个层次遍历. 依旧利用之前层次遍历的代码,每次大的循环存储的是一行的节点,最后一个节点就是想要的那个节点 class Solution { public: vector<int> rightSideView(TreeNode* root) { vector<int> result; if(root == NULL) return resul…
