Remove Nth Node from End of Linked List
You are given a singly linked list with 'N' nodes, each containing integer data, and an integer 'K'. Your goal is to remove the 'K'th node counting from the end of this linked list.
Input:
The first line contains an integer 'T', representing the number of test cases to be processed. Each test case contains:
1. An integer 'K', the 1-based index from the end of the node to remove.
2. A sequence of integers representing the elements of the linked list, ending with -1 (which should not be part of the list).
Output:
For each test case, output a single line containing the updated linked list in a linear form, with each element separated by a space, and end the list with -1.
Example:
Input:
1
2
1 2 3 4 -1
Output:
1 2 4 -1
Constraints:
1 <= T <= 5
0 <= N <= 10^5
0 <= K <= N
1 <= DATA <= 10^9
andDATA ≠ -1
- Time Limit: 1 second
Note:
The function is provided for you to implement; no need to print anything as output handling is already taken care of.
