Structures are very useful when we want to create Linked Lists and Trees. Here we will learn to create a Linked List struct.

Input Format:
The first line of testcase contains T denoting the number of testcases. T testcases follow. Each testcase contains two lines of input. The first line contains N denoting the number of nodes of the linked list. The second line contains the elements of the linked list.

Output Format:
For each testcase, in a new line, print the length of the linked list.

Your Task:
Since this is a function problem, you don't need to take any input. Just complete the provided struct. All the other functions of the linked-list are already implemented.

1 <= T <= 100
1 <= N <= 100


1 2 3 4 5


1->2->3->4->5->NULL is the linked list formed. The length is 5

** For More Input/Output Examples Use 'Expected Output' option **
