Let SLLdel be a function that deletes a node in a singly-linked list given a pointer to the node and a pointer to the head of the list. Similarly, let DLLdel be another function that deletes a node in a doubly-linked list given a pointer to the node and a pointer to the head of the list.
Let n denote the number of nodes in each of the linked lists. Which one of the following choices is TRUE about the worst-case time complexity of SLLdel and DLLdel?
A
SLLdel is O(1) and DLLdel is O(n)
B
Both SLLdel and DLLdel are O(log(n))
C
Both SLLdel and DLLdel are O(1)
D
SLLdel is O(n) and DLLdel is O(1)

Correct : d
