|
|
|
;Task:
|
|
Implement a FIFO queue.
|
|
|
|
Elements are added at one side and popped from the other in the order of insertion.
|
|
|
|
|
|
Operations:
|
|
* push (aka ''enqueue'') - add element
|
|
* pop (aka ''dequeue'') - pop first element
|
|
* empty - return truth value when empty
|
|
|
|
|
|
Errors:
|
|
* handle the error of trying to pop from an empty queue (behavior depends on the language and platform)
|
|
|
|
|
|
;See:
|
|
* [[Queue/Usage]] for the built-in FIFO or queue of your language or standard library.
