1. Remove the Kth Node from the End of a Linked List You are given a singly Linked List with 'N' nodes containing integer data and an integer 'K'. Your task is to delete the Kth node from the end of this Linked List. Input: The first line of input contains an integer 'T', the number of test cases or queries. For each test case: - The first line contains an integer 'K', indicating the position (1-based) from the end of the list to be removed. - The second line lists the elements of the singly linked list, separated by spaces, ending with -1. The value -1 is a terminator and not a part of the list. Output: For each test case, output a single line containing the updated linked list with elements separated by a single space, concluding the list with -1. Print each test case on a separate line. Example: Input: 1 - 2 3 4 -1 Output: 1 2 4 -1 Constraints: 1 <= 'T' <= 5 0 <= 'N' <= 105 0 <= 'K' <= 'N' 1 <= 'DATA' <= 109 and 'DATA' != -1 Time Limit: 1 sec. Note: You only need to implement the function. Do not print anything as it will be handled for you.
