Remove a node from the end of the doubly linked list

A doubly linked list is a data structure in which each node contains a value and two pointers, one pointing to the previous node and the other pointing to the next node in the sequence. The last node in the list is referred to as the tail, while the first node is referred to as the head.

If you want to remove a node with value x from the end side of a doubly linked list, you would start by traversing the list from the tail until you find a node with a value of x. Once you have located the node, you can remove it by updating the pointers of its previous and next nodes to point to each other, effectively bypassing the node to be removed.

Here are the steps to remove a node with value x from the end side of a doubly linked list:

1. Start at the tail node of the doubly linked list.
2. Traverse the list towards the head, checking each node for a value of x.
3. If you find a node with value x, update its previous node's next pointer to point to the node after the current node.
4. If the node to be removed is not the tail, update the next node's previous pointer to point to the previous node.
5. If the node to be removed is the tail, update the tail pointer to point to the previous node.
6. Free the memory allocated to the node to be removed.
