(1) implement the following functions of a Queue using an integer array: • queue_init(): Make the queue empty empty(): return true if the queue is empty. Return otherwise • enqueue(val): add the item val to the queue • dequeue(): remove the item least recently added to the queue front(): return the item least recently added to the queue, but do not remove it. (ii) the program reads in integer values as input: for a positive integer input value greater than 0, the program will insert the value into the queue, i.e. enqueue • for any negative integer input value, the program will return the least recently added value from the queue if it is non-empty, i.e. front for the input value 0, the program will remove the least recently added

A(n) array can be used in an array implementation of a queue to avoid an overflow error at the rear of the queue when the queue is not full.
Queue Simulation Create a java program that will simulate Queue operations using 1-D array representation.Each operation is dependent from each other and it's carried out in the next question in a sequential order. Given: A Queue with 10 elements.
A queue and a deque data structure are related concepts. Deque is an acronym meaning "double-ended queue." With a deque, you may insert, remove, or view from either end of the queue, which distinguishes it from the other two. Use arrays to implement a deque
Radix Sorting Algorithm In C++, implement the radix sorting algorithm using a queue class.Steps: Create a queue filled with 10 random integers between 1000 and 9999. Next, create a list of 10 empty queues (0-9 digit bins), then dequeue each number from the main queue and enqueue them into the correct digit bin. Dequeue the numbers from each digit bin in order and enqueue them back into the main queue. Repeat the process for every digit (tens, hundreds, thousands, etc.) Finally, print the sorted list.
Hello Kindly Find the attached question Thank you
3- Write a program that randomly generates 10 numbers (between 1 and 8), inserts into queue and then finds how many distinct elements exist in the queue. Example 1: Example 2: Queue: 2 40 3 3 2 18 4 18 18 3 Queue: 1 1 4 33 16 16 4 16 4 Output: 5 Output: 4 Notes: • You must use ONLY queue data structure. Don't use other different data structures like string or normal (pure) array or stack or array list. • Don't write any other method in the Qeueu class. All methods must be written in the main program.

In a queue implementation using array of size 5, the array index starts with 0 where head and tail values are 3 and 4 respectively. Determine the array index at which the insertion of the next element will take place. 0 5 1 2
With the concepts of Queue Data Structure, write the functions performing the following tasks: 1. Insertion of an element in the Queue i.e. enqueue() 2. Deletion of an Element from the Queue i.e. dequeue() 3. Display All Elements in the Queue i.e. dispqueue() 4. Display the Element at the Front i.e. dispfront() 5. enqueue() the Queue with the elements in ascending order. After that, use the above four functions to display the same elements in the Queue in descending order.
java program: A linked queue is a single linked list in which: The first node of the linked list is both the front of the queue and the rear of the queue. The first node of the linked list is the rear of the queue and the last node of the linked list is the front of the queue. The first node of the linked list is the front of the queue and the last node of the linked list is the rear of the queue. The last node of the linked list is both the front of the queue and the rear of the queue.
10. 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 QUE(queue Q) { int i ; if (!isEmpty(Q)) { i = delete(Q); QUE(Q); insert(Q, i); } } What operation is performed by the function QUE assuming the elements 1, 2, 3, 4 are in the queue ? %D Leaves the queue unchanged Empties the queue Q Reverse the order of the elements in queue Q Deletes the elements of the queue Q from the front and inserts it at the rear of the Queue Qkeeping the other elements in the same Ogen
