What is the time complexity of the dequeue operation in a queue implemented using an array with pointers to the front and rear?O(1)O(n)O(log n)O(n log n)

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

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

Consider a queue implemented as an array. The queue has a maximum capacity of 5. Initially, the queue is empty. After performing the following operations: enqueue(1), enqueue(2), enqueue(3), dequeue(), enqueue(4), enqueue(5), what will be the front and rear pointers respectively?front = 0, rear = 4front = 1, rear = 4front = 1, rear = 0front = 0, rear = 3

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))

What is the time complexity of searching for an element in a queue of size n if you are given a pointer to both the head and the tail of the queue?O(n)O(1)O(log(n))O(nlog(n))O(2^n)O(n!)O(n^2)
