Question

Evaluate the following code to determine what value will be at the front of the queue after the code completes.

myqueue q = new myqueue();
q.add(38); q.add(56);q.add(73);

Answer 1

The value at the front of the queue after the code operations is 38, as it is the first value added to the queue and the queue behaves in a first-in, first-out manner.

Step-by-step explanation:

The student asked about determining the value that will be at the front of the queue after executing a series of operations on a my queue object. Assuming that the my queue works as a standard queue where elements are added at the end and removed from the front, the operations performed are:

• Add 38 to the queue.
• Add 56 to the queue.
• Add 73 to the queue.

Since a queue is a first-in, first-out (FIFO) data structure, the first value added will be at the front of the queue until it is removed. In this scenario, 38 would be the value at the front of the queue after these operations, as it was the first to be added and has not been removed.
