Which one is a pile of plates?
Short answer. A stack.
What does a queue use?
front and rear.
Remember
| Stack: LIFO, push and pop |
| Queue: FIFO, front and rear |
A pile of plates and a ticket line. Which is which? T is the top. Push eight last, pop gives eight first. A queue instead uses front and rear. Remember two things. A stack is last in, first out. A queue is first in, first out.
