4.5.1 Queues

In This lesson, you are going to explore another data structure, the Queue. Queues are very similar to stacks with one notable exception. Data in a stack is managed last-in, first-out (LIFO), but in a queue the data is managed first-in, first-out. (FIFO)

Like a stack, queues can store a list of items and you have limited access to the members of the queue.
