Which of the following operations can be performed in O(1) time on a linked list

Which of the following operations can be performed in O(1) time on a linked list?

Which of the following operations can be performed in O(1) time on a linked list?

Step 1: Understand what a linked list is. A linked list is a data structure where each element (node) points to the next one.
Step 2: Identify the head of the linked list. The head is the first node in the list.
Step 3: Know what O(1) time means. O(1) time means the operation takes the same amount of time regardless of the size of the list.
Step 4: Consider the operation of deleting a node. Deleting a node from the beginning of the linked list means removing the head node.
Step 5: Realize that to delete the head node, you only need to update the head pointer to point to the next node.
Step 6: Since updating a pointer is a constant time operation, deleting from the beginning of a linked list can be done in O(1) time.
