Uiua
Uiua is still developing very quickly, and this code uses the experimental
tuplesfunction, hence the initial directive.Try it Live!
How do you write this, not conceptually but physically. Do you have a char picker open at all times?
Haha, you can do it that way, in fact the online Uiua Pad editor has all the operators listed along the top.
But all the operators have ascii names, so you can type e.g.
IsSmall = reduce mul mul fork(>0|<4) abs drop neg 1 - rot 1 dupand the formatter will reduce that toIsSmall ← /××⊃(>0|<4)⌵↘¯1-↻1.whenever you save or execute code.That works in the Pad, and you can enable similar functionality in other editors.
i can only imagine doing it with a drawing tablet
I like to assume people using array programming languages just have a crystal ball that they use to call upon magic runes on the screen
This looks so alien! Does it work with the full set? The comment says 5, choose 4, but I guess it’s written as n, choose n-1?
Yes, it should do. I do run the solutions against the live data, but sometimes tweak the solutions afterwards, so can't always guarantee them :-). I left the comment as 5 choose 4 as it felt clearer in the context of the test data.
It does still feel very alien at times, but I do love being able to think about how to adopt a more arrays-based approach to solving these problems.
