* 1379. Find a Corresponding Node of a Binary Tree in a Clone of That Tree
7-
*
8-
* Given two binary trees original and cloned and given a reference to a node target in the original tree.
9-
* The cloned tree is a copy of the original tree.
10-
* Return a reference to the same node in the cloned tree.
11-
* Note that you are not allowed to change any of the two trees or the target node and the answer must be a reference to a node in the cloned tree.
12-
*
13-
* Follow up: Solve the problem if repeated values on the tree are allowed.
14-
*
15-
* Example 1:
16-
* Input: tree = [7,4,3,null,null,6,19], target = 3
17-
* Output: 3
18-
* Explanation: In all examples the original and cloned trees are shown. The target node is a green node from the original tree. The answer is the yellow node from the cloned tree.
19-

20-
* Example 2:
21-
* Input: tree = [7], target = 7
22-
* Output: 7
23-
*
24-
* Example 3:
25-
* Input: tree = [8,null,6,null,5,null,4,null,3,null,2,null,1], target = 4
26-
* Output: 4
27-
*
28-
* Example 4:
29-
* Input: tree = [1,2,3,4,5,6,7,8,9,10], target = 5
30-
* Output: 5
31-
*
32-
* Example 5:
33-
* Input: tree = [1,2,null,3], target = 2
34-
* Output: 2
35-
*
36-
* Constraints:
37-
* The number of nodes in the tree is in the range [1, 10^4].
38-
* The values of the nodes of the tree are unique.
39-
* target node is a node from the original tree and is not null.
40-
