Problem Statement

Reduce is a function or method that is used to take the values in an array or a list and apply a function to successive members of the list to produce (or reduce them to), a single value.

Show how reduce (or foldl or foldr etc), work (or would be implemented) in your language.

Let's start with the solution:

!/ ^+ [1 2 3] ; returns 6

@fold ^+ 1 [1 2 3] ; returns 7
