Given a single linked list and an integer x your task is to complete the function **deleteAllOccurances** which deletes all occurences of a key x present in the linked list. The function takes two arguments: the head of the linked list and an integer x. The function should return the head of the modified linked list.

**Input:**

The first line of input contains an element T, denoting the no 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 no 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.

**Output:**

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

**Constraints:**

1<=T<=300

1<=N<=100

1<=x<=N
