Traversal operations in singly and doubly linked lists have some interesting differences.

Singly Linked Lists

• Direction: You can only go forward. This means you start at the first node (called the head) and visit each node one by one until you reach the end.
• Simplicity: Since there is just one pointer to follow (called the next pointer), it’s easy to move through the list. You only need to keep track of one node at a time.

Doubly Linked Lists

• Two Directions: You can move in both directions—forward and backward! Each node has two pointers: one for the next node and one for the previous node.
• More Options: This makes it easier to move back through the list. You don’t have to start over from the head. Also, if you want to delete or add nodes, having the backward pointer gives you more information.

In summary, both types of lists let you go through the items one by one. But doubly linked lists offer more flexibility, although they use more memory because they have extra pointers.
