Question

17. What is the output of this pseudocode?
while (!queue.isEmpty())
print(queue.dequeue());

Consider this pseudocode:
String items [] = {"A", "B", "C", "D", "A", "F"};
// create an empty stack, queue, and set.
Stack stack = new Stack();
Queue queue = new Queue();
Set set = new Set();
//loop through all items and add them to the stack, queue, and set
for(String item: items) {
stack.push(item);
queue.enqueue(item);
set.add(item);
}
