Consider the following statements:i. First-in-first out types of computations are efficiently supported by STACKS.ii. Implementing LISTS on linked lists is more efficient than implementing LISTS on an array for almost all the basic LIST operations.iii. Implementing QUEUES on a circular array is more efficient than implementing QUEUES on a linear array with two indices.iv. Last-in-first-out type of computations are efficiently supported by QUEUES.Which of the following is correct?
Suppose you are given an implementation of a queue of integers. The operations that can be performed on the queue are:i. isEmpty (Q) — returns true if the queue is empty, false otherwise.ii. delete (Q) — deletes the element at the front of the queue and returns its value.iii. insert (Q, i) — inserts the integer i at the rear of the queue.Consider the following function:void f (queue Q) {int i ;if (!isEmpty(Q)) { i = delete(Q); f(Q); insert(Q, i); }}What operation is performed by the above function f ?
