To delete the nth node from the end in a linked list, we can use a two-pointer approach.
Use two pointers, one to traverse the list and another to keep track of the nth node from the end.
Move the second pointer n steps ahead of the first pointer.
When the second pointer reaches the end of the list, the first pointer will be at the nth node from the end.
Adjust the pointers to delete the nth node.
