Given a Binary Tree having random pointers clone the Binary Tree. The task is to complete the function** cloneTree** which take one argument the root of the tree to be copied and should return the root of the cloned tree.

**Input:**

The first line of input contains the no of test cases. Then T test cases follow. Each test case contains 2 lines the first line contains and integer N denoting the no of edges of the tree and then in the next line are N space separated queries .The query on tree are of three types

a) a b L (Represents that b is the left child of a)

b) a b R (Represents that b is the right child of a)

c) a b X (Represents a random pointer from node a to node b)

**Output:**

Your function should return the root of the cloned tree. The output will be 1 if the tree is successfully cloned.

**Constraints:**

1 <=T<= 30

1 <=Number of nodes<= 100

1 <=Data of a node<= 1000
