701. Insert into a Binary Search Tree 经典题目:给定一个二叉搜索树,插入一个值为val的新节点 /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL), right(NULL) {}...
Given the tree: 4 / \ 2 7 / \ 1 3 And the value to insert: 5 1. 2. 3. 4. 5. 6. 7. You can return this binary search tree: 4 / \ 2 7 / \ / 1 3 5 1. 2. 3. 4. 5. This tree is also valid: 5 / \
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...
