What is the time complexity of enqueue() and dequeue() operations in a typical queue implemented using a linked list?Group of answer choicesO(n) for both enqueue() and dequeue()O(n) for enqueue() and O(1) for dequeue()O(1) for enqueue() and O(n) for dequeue()O(1) for both enqueue() and dequeue()

The stack using queue(with only enqueue and dequeue operations), how many queues will we need for implementing?Options1234

A queue is implemented using an array such that ENQUEUE and DEQUEUE operations are performed efficiently. Which one of the following statements is CORRECT (n refers to the number of items in the queue)? [GATE CSE 2016]Question 4Answera.Both operations can be performed in O(1) timeb.Worst case time complexity for both operations will be Ω(log n)c.The worst-case time complexity for both operations will be Ωd.At most one operation can be performed on O(1) time but the worst-case time for the other operation will be Ω

What is the time complexity of “pushing” an element into a queue if you are given a pointer to both the head and the tail of the queue?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))
