Question
Consider the following code segment , The variable q is an object of type Queue, the variable s is an object of type Stack.
- peek method looks at the first element in the queue without removing it.
- the remove method removes the first element from the queue.
- add method adds an element to the and of the queue or add an element to the top of the stack.
- pop method removes an element from the top of the stack
What would be the content of the variable q (8 numbers) after we complete the second while loop in the code
for (int i = 30; i <= 40; i ++)
{
if(i % 3 == 0)
q.add(i);
}
while (!q.isEmpty()) {
s.add(q.peek());
s.add(q.peek());
q.remove();
}
while (!s.isEmpty()) {
q.add(s.pop());
}
