Q1. Delete nth node from end in linked list
Ans. 
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.
