Question

C++

You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST.

Example 1: diagram for example 1 attached

Input: root = [4,2,7,1,3], val = 5 Output: [4,2,7,1,3,5] Explanation: Another accepted tree is:

Example 2:

Input: root = [40,20,60,10,30,50,70], val = 25 Output: [40,20,60,10,30,50,70,null,null,25]

Example 3:

Input: root = [4,2,7,1,3,null,null,null,null,null,null], val = 5 Output: [4,2,7,1,3,5]

Constraints:

The number of nodes in the tree will be in the range [0, 10⁴].
-10⁸ <= Node.val <= 10⁸
All the values Node.val are unique.
-10⁸ <= val <= 10⁸
It's guaranteed that val does not exist in the original BST.
