Question 1 of 40Assessment

What is the time complexity of deleting a node in a singly linked list if you are only given a pointer to that specific node (not the head)?

A. O(n) because you must traverse from the head to find the previous node to update its next pointer.

B. O(1) if you copy the data from the next node into the current node and delete the next node.

C. It is impossible to delete the node without a reference to the head or the previous node in the list.

D. O(1) if the list is circular; otherwise, it is an undefined operation in standard singly linked lists.
