Solution:

class Solution {
    public final TreeNode getTargetCopy(final TreeNode original, final TreeNode cloned, final TreeNode target) {
        if (original == null) {
            return null;
        }
        if (original.equals(target)) {
            return cloned;
        }
        TreeNode leftResult = getTargetCopy(original.left, cloned.left, target);
        if (leftResult != null) {
            return leftResult;
        }
        return getTargetCopy(original.right, cloned.right, target);
    }
