Chapter 18: Problem 14

Suppose the following operations are performed on an empty queue: enqueue (5) enqueue (7) enqueue( 9 ) enqueue (12)

Short Answer

Expert verified
Answer: The resulting queue after performing the given enqueue operations is [5, 7, 9, 12].

Step by step solution

01

Initialize an empty queue

Begin with an empty queue represented as [ ].
02

Perform the first enqueue operation

Enqueue the number 5 into the queue: enqueue(5). The queue now looks like this [5].
03

Perform the second enqueue operation

Enqueue the number 7 into the queue: enqueue(7). The queue now looks like this [5, 7].
04

Perform the third enqueue operation

Enqueue the number 9 into the queue: enqueue(9). The queue now looks like this [5, 7, 9].
05

Perform the fourth enqueue operation

Enqueue the number 12 into the queue: enqueue(12). The queue now looks like this [5, 7, 9, 12]. After performing all the enqueue operations, the final queue is [5, 7, 9, 12].
