If we enqueue( ) the Integers 11, 8, 7, 12 into a queue in that order, and then a call to dequeue( ) will yield
a. null
b. max
c. 8
d. 7
e. 12.
f. 11

Suppose we want to implement a circular queue using an array that has an initial capacity (maximum number of elements) MAX. A circular queue is like a regular queue except that elements can be enqueued or dequeued by wrapping around it. Assume we enqueue on the tail and dequeue from the head. An example circular queue with sample operations is shown below: head head tail head tail tail head Enqueue(9) a) Write a program in C that implements this circular...

In Java, create a program implementing the functionalities of a standard queue in a class called Queue3503. You will test the functionalities of the Queue3503 class from the main() method of the Main class. In a queue, first inserted items are removed first and the last items are removed at the end (imagine a line to buy tickets at a ticket counter). Do NOT change your class name from "Main". The Main class should come first in your code. Your filename should be "Main.java". The Queue3503 class will contain:...

You are going to create a Queue. (alternately you can create a list and simply implement enqueue and dequeue functions in the List – that will technically make it a queue). You will fill the first list with numbers consecutively numbered from 2 to n where n is entered by the user (we will call this Q1). When creating your Queue object use the correct function names for enqueue and dequeue functions. Again – sorry, cannot use an Javascript array...
