To insert a Node iteratively in a BST tree, we will need to traverse the tree using two pointers. public static TreeNode insertionIterative(TreeNode root, int value) { TreeNode current, parent; TreeNode tempNode = new TreeNode(value); if (root == null) { root = tempNode; return root...
Note that there may exist multiple valid ways for the insertion, as long as the tree remains a BST after insertion. You can return any of them. For example, Given the tree: 4 / \ 2 7 / \ 1 3 And the value to insert: 5 You can return this binary search tree: 4 / \ 2 7...

You are given therootnode of a binary search tree (BST) and avalueto insert into the tree. Returnthe root node of the BST after the insertion. It isguaranteedthat the new value does not exist in the original BST. Noticethat there may exist multiple valid ways for the insertion, as lon...
Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Note that there may exist multipl...

Given the tree: 4 / \ 2 7 / \ 1 3 And the value to insert: 5 You can return this binary search tree: 4 / \ 2 7 / \ / 1 3 5 This tree is also valid: 5 / \ 2 7 / \ 1 3 \ 4 分析 题意:把一个新值查到二叉搜索树中,返回的树满足二叉搜索树的规则即可。
