void connect(TreeLinkNode *root) { while (root) { //每一层循环时重新初始化 TreeLinkNode *prev = nullptr; TreeLinkNode *next = nullptr; //对于每一层 for (; root; root = root->next) { //每一层开始时,记录下一层的起始结点 if (!next)next = root->left ? root->left : root->right; i…

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 *…
