You’re given the pointer to the head node of a linked list and the
position of a node to delete. Delete the node at the given position and
return the head node. A position of 0 indicates head, a position of 1
indicates one node away from the head and so on. The list may become
empty after you delete the node.
Input Format
You have to complete the
Output Format
Delete the node at the given position and
Sample Input
1 --> 2 --> 3 --> NULL, position = 0
1 --> NULL , position = 0
Sample Output
1. 0th position is removed, 1 is deleted from the list.
2. Again 0th position is deleted and we are left with empty list.

Input Format
You have to complete the
Node* Delete(Node* head, int position)
method which takes two arguments - the head of the linked list and the
position of the node to delete. You should NOT read any input from
stdin/console. position
will always be at least 0 and less than the number of the elements in the list.Output Format
Delete the node at the given position and
return
the head of the updated linked list. Do NOT print anything to stdout/console.Sample Input
1 --> 2 --> 3 --> NULL, position = 0
1 --> NULL , position = 0
Sample Output
2 --> 3 --> NULL
NULL
Explanation 1. 0th position is removed, 1 is deleted from the list.
2. Again 0th position is deleted and we are left with empty list.
