Question 1:

StackOfStrings s = new StackOfStrings(); while (!StdIn.isEmpty()) { String item = StdIn.readString(); if (!item.equals("-")) s.push(item); else if (s.isEmpty()) StdOut.println("BAD INPUT"); else StdOut.print(s.pop() + " "); }

Suppose the input is " one two three - four five - - six - seven " What would be the second word in the output?

Question 1 options:

	two
	four
	six
	none of these

Question 2:

Consider the code segment below:

 Node x = new Node(2); Node a = new Node(3); Node c = new Node(4); Node b = new Node(7); x.next = a; c.next = x; b.next = c;

If we print the list starting at x, the result would be:

Question 2 options:

7 3 2 4
7 3 2
7 4 2 3
none of these
