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 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 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.

**User Task:**

The task is to complete the function **deleteAllOccurances**() which should delete all the occurrences of given number x from the list.

**Constraints:**

1 <= T <= 300

1 <= N <= 100

1 <= x <= N
