How do I search for a value in a doubly linked list?

To search for a value in a doubly linked list, you can traverse the list starting from the head node.

What if the value is not found?

If the value is not found, you can return a message indicating that the value does not exist in the list.

Can you show me a code example?

Sure! Here's a simple Python example:

class Node:
    def __init__(self, data):
        self.data = data
        self.prev = None
        self.next = None

class DoublyLinkedList:
    def __init__(self):
        self.head = None

    def search(self, value):
        current = self.head
        while current:
            if current.data == value:
                return current
            current = current.next
        return None
