What does this method do? public void undefined() { if(size < 2) return; if(size == capacity) reallocate(); rear = (rear + 1)%capacity; int f = (front + 1)%capacity; theData[rear] = theData[f]; size++; } Makes the front as rear and the rear as front, if the number of elements in the queue is at least 2. Adds the front element of the queue at the rear of the queue, if the number of elements in the queue is at least 2. Adds the second element of the queue at the rear of the queue, if the number of elements in the queue is at least 2. Exchanges the first and the last elements of the queue, if the number of elements in the queue is at least 2.

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.

Anytime before your job prints, you can access the queueto remove it. Thus, some queues support a remove operation. Add this method tothe queue implementations. The method should expect an integer index as anargument. It should then remove and return the item in the queue at that position(counting from position 0 at the front to position n –1 at the rear). Use this Python template: class Queue:'''TODO: Remove the "pass" statements and implement each methodAdd any methods if necesssaryDON'T use any builtin queue class to store your items'''def __init__(self): # Constructor functionpassdef isEmpty(self): # Returns True if the queue is empty or False otherwisepassdef len(self): # Returns the number of items in the queuepassdef peek(self): # Returns the item at the front of the queuepassdef add(self, item): # Adds item to the rear of the queuepassdef pop(self): # Removes and returns the…
- Assume that you have the Queue implementation.Write a method in Queue class so that this method checks whether the number that you want to add is divided by 3 or not. If the number is divided by 3, add it and return true if the operation is successful.What does the following function do?void mystery(queueType<int>& q){stackType<int> s;while (!q.isEmptyQueue()){s.push(q.front());q.deleteQueue();}while (!s.isEmptyStack()){q.addQueue(2 * s.top());s.pop();}}Working with Queues 1. Create a method on the Queue class that calculates the number of times a given value occurs in the queue. int Queue::count( const T & data ) const; Example: count(…) function Result Queue count (5) 3 front->(1) (1) (5) (3) (5) (5) (2)<-back count (10) 0 front->(1) (1) (5) (3) (5) (5) (5) (2)<-back 2.
