Wikipedia on [queues](http://en.wikipedia.org/wiki/Queue_(abstract_data_type)).
|
|
|
|
The opposite of the Stack, the Queue is a FIFO data structure - First In, First Out.
|
|
|
|
#### Visualization
|
|
|
|
A music playlist works like a queue.
|
|
|
|
|Tommy Tutone - 8675309 Jenny|

|
|
|
|Europe - The Final Countdown|
|

|Dio - Holy Diver|

|
The enqueue operation will add a song to the end. The dequeue operation will pop off the front.
|
|
|
|
#### Implementation
|
|
|
|
You will need to create a Queue class that holds the following methods:
|
|
|
|
- enqueue
|
|
|
|
- dequeue
|
|
|
|
- is_empty
|
|
|
|
- get_front.
