public class Solution extends Object
938 - Range Sum of BST\. Easy Given the `root` node of a binary search tree and two integers `low` and `high`, return _the sum of values of all nodes with a value in the **inclusive** range_ `[low, high]`. **Example 1:** ![](https://assets.leetcode.com/uploads/2020/11/05/bst1.jpg) **Input:** root = [10,5,15,3,7,null,18], low = 7, high = 15 **Output:** 32 **Explanation:** Nodes 7, 10, and 15 are in the range [7, 15]. 7 + 10 + 15 = 32. **Example 2:** ![](https://assets.leetcode.com/uploads/2020/11/05/bst2.jpg) **Input:** root = [10,5,15,3,7,13,18,1,null,6], low = 6, high = 10 **Output:** 23 **Explanation:** Nodes 6, 7, and 10 are in the range [6, 10]. 6 + 7 + 10 = 23. **Constraints:** * The number of nodes in the tree is in the range [1, 2 * 104]. * 1 <= Node.val <= 105 * 1 <= low <= high <= 105 * All `Node.val` are **unique**.
