What is the key difference between a singly linked list and a doubly linked list?
Singly linked lists can only be traversed in one direction, while doubly linked lists can be traversed in both directions.

To delete a node from a Singly Linked List at a given index
What does the variable 'x = -1' indicate in the 'deletes' function?
Unsuccessful deletion of the node
What is the significance of 'index < 1 || index > length()' in the 'deletes' function?
Checking if the index is within a valid range
What operation is performed when 'index == 1' in the 'deletes' function?
Deleting the first node of the linked list
What is the role of 'q' in the 'deletes' function when 'index != 1'?
To store the previous node before deletion
What happens if 'index' exceeds the total length of the linked list in the 'deletes' function?
