Node at a given index in linked list
Basic Accuracy: 46.18% Submissions: 47743 Points: 1

Given a singly linked list with N nodes and a number X. The task is to find the node at the given index (X)(1 based index) of linked list.

Input:
First line of input contains number of testcases T. For each testcase, first line of input contains space seperated two integers, length of linked list and X.

Output:
For each testcase, there will be single line of output containing data at Xth node.

The task is to complete the function GetNth() which takes head reference and index as arguments and should return the data at Xth position in the linked list.

Constraints:
1 <= T <= 30
1 <= N <= 100
K <= N
1 <= value <= 103

Example:
Input:

2
6 5
1 2 3 4 657 76
10 2
8 7 10 8 6 1 20 91 21 2

Output:
657
7

Explanation:
Testcase 1:
Element at 5th index in the linked list is 657 (1-based indexing).
