| - * 1038. Binary Search Tree to Greater Sum Tree |
7 |
| - * |
8 |
| - * Given the root of a binary search tree with distinct values, |
9 |
| - * modify it so that every node has a new value equal to the sum of the values of the original tree that are greater than or equal to node.val. |
10 |
| - * As a reminder, a binary search tree is a tree that satisfies these constraints: |
11 |
| - * |
12 |
| - * The left subtree of a node contains only nodes with keys less than the node's key. |
13 |
| - * The right subtree of a node contains only nodes with keys greater than the node's key. |
14 |
| - * Both the left and right subtrees must also be binary search trees. |
15 |
| - * |
16 |
| - * |
17 |
| - * Example 1: |
18 |
| - * 4(30) |
19 |
| - * / \ |
20 |
| - * 1(36) 6(21) |
21 |
| - * / \ / \ |
22 |
| - * 0(36) 2(35) 5(26) 7(15) |
23 |
| - * \ \ |
24 |
| - * 3(33) 8(8) |
25 |
| - * |
26 |
| - * Input: [4,1,6,0,2,5,7,null,null,null,3,null,null,null,8] |
27 |
| - * Output: [30,36,21,36,35,26,15,null,null,null,33,null,null,null,8] |

30 |
| - * Note: |
31 |
| - * |
32 |
| - * The number of nodes in the tree is between 1 and 100. |
33 |
| - * Each node will have value between 0 and 100. |
34 |
| - * The given tree is a binary search tree.*/ |
