Given a binary search tree, print the elements in-order iteratively without using recursion.Note:Before you attempt this problem, you might want to try coding a pre-order traversal iterative solution first, because it is easier. On the other hand, coding a post-order iterative version is a ...
第一种,先跑左子树的DFS:如果不满足,返回false. 左子树分支判断完成后,pre = root.left(因为唯一给pre赋值的语句是pre = root,所以运行完dfs(root.left)之后,pre = root.left)。 然后,若pre.val,也就是root.left.val,大于等于root.val的话,不满足BST定义,也返回false; 否则,继续执行pre = root,(现在去...
That left or right child node becomes the parent's new left or right child through recursion (line 7 or 9). Case 3: Node has both left and right child nodes. The in-order successor is found using the minValueNode() function. We keep the successor's value by setting it as the ...
-105<= Node.val <= 105 Follow up:Could you do that without using any extra space? (Assume that the implicit stack space incurred due to recursion does not count). Copyright ©️ 2025 LeetCode All rights reserved Case 1 Case 2 [1,null,2,2]...
Here is an example of an optimized C++ implementation using lazy deletion and recursion: #include struct TreeNode { int val; TreeNode* left; TreeNode* right; bool deleted; // added for lazy deletion TreeNode(int x) : val(x), left(nullptr), right(nullptr), deleted(false) {} }; Tree...
Follow up:Could you do that without using any extra space? (Assume that the implicit stack space incurred due to recursion does not count). 粗暴解法,直接hash计数然后找出最大计数的值。 # Definition for a binary tree node. # class TreeNode(object): ...
Follow up: Could you do that without using any extra space? (Assume that the implicit stack space incurred due to recursion does not count). 思路: 这道题左子节点可能等于根节点和右子节点,宜使用中序遍历求解。此外,这道题限制空间复杂度O(1),不少sulotion采用hashmap或者list,如果遇到1,2,3,4...
