max package:universum

The largest element of a NonEmpty.

>>> maximum (1 :| [2,3,4,5])
5

The largest element of a NonEmpty with respect to the given comparison function.

The largest element of a non-empty structure. This function is non-total and will raise a runtime exception if the structure happens to be empty. A structure that supports random access and maintains its elements in order should provide a specialised implementation to return the maximum in faster than linear time.

Examples

Basic usage:

>>> maximum [1..10]
10

>>> maximum []
*** Exception: Prelude.maximum: empty list

>>> maximum Nothing
*** Exception: maximum: empty structure

WARNING: This function is partial for possibly-empty structures like lists.

The largest element of a non-empty structure with respect to the given comparison function.

Examples

Basic usage:

>>> maximumBy (compare `on` length) ["Hello", "World", "!", "Longest", "bar"]
"Longest"
