Delete xth node from a singly linked list. Your task is to complete the method deleteNode() which takes two arguments: the address of the head of the linked list and an integer x. The function returns the head of the modified linked list.

The first line of input contains an element T, denoting the number of test cases. Then T test cases follow. Each test case contains three lines. The first line of each test case contains an integer N denoting the number of elements of the linked list. Then in the next line are N space separated values of the linked list. The third line of each test case contains an integer x.

The output for each test case will be the space separated value of the returned linked list.

User Task:
The task is to complete the function deleteNode() which should delete the node at required position.

1 <= T <= 300
2 <= N <= 100
1 <= x <= N

Testcase 1:
 After deleting the node at 3rd position (1-base indexing), the linked list is as 1-> 3.
Testcase 2: After deleting the node at 2nd position (1-based indexing), the linked list is as 1-> 2-> 9.
