- * 669. Trim a Binary Search Tree
- *
- * Given a binary search tree and the lowest and highest boundaries as L and R,
- * trim the tree so that all its elements lies in [L, R] (R >= L).
- * You might need to change the root of the tree, so the result should return the new root of the trimmed binary search tree.

- Example 1:
-
- Input:
-   1
-  / \
- 0   2
-
- L = 1
- R = 2
-
- Output:
- 1
-  \
-  2
-
- Example 2:
-
- Input:
-  3
- / \
-0   4
- \
- 2
- /
-1
-
- L = 1
- R = 3
