The APL Challenge continues the tradition of the APL Problem Solving Competition, which Dyalog Ltd ran from 2008 until 2023, but is aimed specifically at newcomers to APL, and consists of ten entry-level problems.<ref>Dyalog Ltd.

Because each index can appear multiple times in the array of indices, or not at all, each result element is a list of all the values placed there. Group is ambivalent: in the dyadic case, the left argument is the array of indices and the right argument is the array of values. In the monadic case, the right argument gives the result indices and...")

In APL it's usually written with the Power operator as <syntaxhighlight lang=apl inline>(f⍣¯1) x</syntaxhighlight>. While some functions such as Reverse have an obvious exact inverse, others might have no valid inverse or many possible choices for a given result. Treatment of these cases varies among dialects, but...")
