Given a root of the tree you need to perform AVL tree deletion operations on it. You need to complete the method **delelteNode** which takes 2 arguments the first is the root of the tree and the second is the value of the node to be deleted.The function should return the root of the modified tree.

**Note:** Your code will be checked for each insertion and will produce an output 1 if all the nodes for a particular test case were correctly inserted else 0.

**Input:**

The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains 2 lines . The first line of each test case contains an integer N denoting the no of nodes to be inserted in the AVL tree and in the next line are N space separated values denoting the values of the nodes to be inserted to the tree. And last line denotes the element to be deleted.

**Output:**

For each test case output will be 1 if the node was correctly deleted else 0.

**Constraints:**

1<=T<=100

1<=N<=100

**Example(To be used only for expected output):
Input:**
