/**
 * 1379. Find a Corresponding Node of a Binary Tree in a Clone of That Tree
 *
 * Given two binary trees original and cloned and given a reference to a node target in the original tree.
 * The cloned tree is a copy of the original tree.
 * Return a reference to the same node in the cloned tree.
 * 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.
 *
 * Follow up: Solve the problem if repeated values on the tree are allowed.
 *
 * Example 1:
 * Input: tree = [7,4,3,null,null,6,19], target = 3
 * Output: 3
 * 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.
 *
 * Example 2:
 * Input: tree = [7], target =  7
 * Output: 7
 *
 * Example 3:
 * Input: tree = [8,null,6,null,5,null,4,null,3,null,2,null,1], target = 4
 * Output: 4
 *
 * Example 4:
 * Input: tree = [1,2,3,4,5,6,7,8,9,10], target = 5
 * Output: 5
 *
 * Example 5:
 * Input: tree = [1,2,null,3], target = 2
 * Output: 2
 *
 * Constraints:
 * The number of nodes in the tree is in the range [1, 10^4].
 * The values of the nodes of the tree are unique.
 * target node is a node from the original tree and is not null.
