a) Consider the following code(assume that pop() returns the Object stored in the stack): Queue q = new LinkedQueue(); Stack s = new LinkedStack(); s.push(1); s.push(8); s.push(7); while (!s.isEmpty()) { q.enqueue(s.pop()); }

Question

a) Consider the following code(assume that pop() returns the Object stored in the stack):

Queue<Integer> q = new LinkedQueue<Integer>();
Stack<Integer> s = new LinkedStack<Integer>();
s.push(1);
s.push(8);
s.push(7);

while (!s.isEmpty()) {
q.enqueue(s.pop());
}
System.out.print(q.dequeue() + ", " + q.dequeue()); // note: a comma and a space character separate the values.

What is the output that is printed when this code executes? (enter exactly what is printed).

b) Consider the following array: 9, 2, 3, 8, 0

We apply selection sort to sort this array in ascending order.

What is the state of the array after the first two rounds of the outer loop?
