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.
java data structure Queue: Q4: A program performs the following operations on an empty queue Q: Q.enqueue(24) Q.enqueue(74) Q.enqueue(34) Q.first() Q.dequeue() Q.enqueue(12) Q.dequeue() Please show the queue contents at the end of these operations. Clearly show the front of the queue.

URGENT URGENT URGENT !!!! Write a void method swapStackwithQueue that takes MyStack and MyQueue Objects as parameters and exchanges the elements. a) The top element of the old stack becomes the rear element of the new queue. b b) and the rear element of the old queue becomes the top element of the new stack. The output should be similar to the image.
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
The front method of the array based queue Select one: a. Change the front but the rear is not changed b. Change the rear but the front is not changed c. Change the front and the rear d. Not change the front and the rear
