FAQs
Question: What is the main difference between an Array and a Linked List? Answer: An Array has a fixed size and stores elements in contiguous memory locations, while a Linked List consists of nodes that can dynamically grow and are linked using pointers.
Question: How do you insert an element in a Linked List? Answer: To insert an element in a Linked List, you need to create a new node and adjust the pointers of the existing nodes to include the new node at the desired position.

Q. In a circular linked list, what is the main characteristic?
A.
Last node points to null
B.
First node points to last node
C.
All nodes are connected in a circle
D.
None of the above
Solution
In a circular linked list, the last node points back to the first node, forming a circle.
Correct Answer:
C
— All nodes are connected in a circle
Q. In a singly linked list, how do you delete a node given only access to that node?
A.
Set the node to null
B.
Copy the next node's data
C.
Change the previous node's pointer
D.
You cannot delete it
Solution
To delete a node in a singly linked list when you only have access to that node, you can copy the data from the next node and then delete the next node.
