Question
What is the time complexity of deletion from the end in a circular doubly linked list? a. O(1) b. O(n) c. O(log n) d. O(log log n)
Solution
The time complexity of deletion from the end in a circular doubly linked list is O(1). This is because in a doubly linked list, we have a pointer to the last node and we can directly access the last node and modify the next and previous pointers accordingly. Hence, the operation can be done in constant time. So, the answer is a. O(1).
