Queue q= new LinkedQueue (8); q.enqueue ("A"); q.enqueue ("B"); q.enqueue ("C"); q.enqueue ("D"); q.enqueue ("E"); q.enqueue ("F"); Stack s= new LinkedStack (8); for (int i=0; i<3; i++) { s.push (q.de queue () ); After all of this code executes, the size of the queue g is -----and the size of the stack is ------ 1, 5 3, 3 4. 2 5, 1
Problem 2: Assume that the methods push(), pop() and isEmpty() methods are defined as they should be in a Stack class. Assume further that the Stack class has a no argument constructor. Write a method that uses the constructor and the methods push(), pop() and isEmpty() for removing and returning the bottom element of a given stack. Note: make sure that you don't include unnecessary spaces in your answers! public T popBottom(Stack stack) { Stack tempStack = new Stack(); Tx = null; if (!stack.isEmpty()) { x = stack.pop(); } while (!stack.isEmpty()) { #04 ; x = stack.pop(); } while (!tempStack.isEmpty()) { #05 ; } return x; }
Is my question submitted.
1. Assume you have a queue with operations: enqueue(), dequeue(), isEmpty(). How would you use the queue methods to simulate a stack, in particular, push() and pop() ? Hint: use two queues, one of which is the main one and one is temporary.

Computer Science CODE IN C++: You have to design and implement a game in which the avatar has to find the hidden treasure in circus. Theonly way to guide the avatar and to find the treasure is to find the shortest path that leads to the hiddentreasure. You, being a developer are bound to use the Queue data structure. Among, depth first search andbreath first search, determine the most suitable algorithm and provide a complete code. Decide the suitablename of the avatar and the game since you are the designer. Data should be taken from the user. Makerelevant assumptions if required
