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...
In the following sections, we’ll see how to search, insert and delete in a BST recursively as well as iteratively. Let’s create our Binary Tree Data Structure first: Note that the above implementation is not a binary search tree because there is no restriction in inserting elements to the...

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。
