Question
Which type of linked list has its last node pointing back to the first node?
- a. Singly linked list
- b. Circular linked list
- c. Doubly linked list
- d. Linear linked list
Solution
The type of linked list that has its last node pointing back to the first node is called a Circular linked list.
Explanation:
- Singly linked list: In this type, each node points to the next node, and the last node points to null, indicating the end of the list.
- Circular linked list: Here, the last node points back to the first node, forming a circle. This allows for continuous traversal of the list.
- Doubly linked list: Each node has two pointers, one pointing to the next node and the other to the previous node, but the last node points to null.
- Linear linked list: This is not a standard term often, but it generally refers to a singly linked list.
Thus, the correct answer is b. Circular linked list.
