reverse -package:text-short

reverse xs returns the elements of xs in reverse order. xs must be finite.

Laziness

reverse is lazy in its elements.

>>> head (reverse [undefined, 1])
1

>>> reverse (1 : 2 : undefined)
*** Exception: Prelude.undefined

Examples

>>> reverse []
[]

>>> reverse [42]
[42]

>>> reverse [2,5,7]
[7,5,2]

>>> reverse [1..]
* Hangs forever *
