Hi,
White Hat Hackers
Explanation
A hacker is a person who uses his or her computer skills in software and hardware to breakdown and bypass security steps in a computer. There are three categories of hackers; white hat hacker, grey hat hacker and the black hat hacker. The black hat hackers write malware to deploy in computers for cyber crime uses. White hat hackers are the opposite of the black hat hackers. White hat hackers are ethical hackers who find security loop holes in systems by using their hacking skills.

Answer:
One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.
Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).
Dequeueing would be:
- For all items in stack1: pop them from stack1 and push them in stack 2.
- Pop one item from stack2, which will be your dequeue result
- For all items in stack2: pop them from stack2 and push them in stack 1.
Hope it makes sense. I'm sure you can draw a diagram.
