[Jprogramming] [Beginner] How to make a function using list pattern matching deterministic

Currently I have these two predicates in my program that I think I can make deterministic. :- pred entry(list(string)::in, list(int)::out) is det. entry(Dirs, Out) :- map((pred(X::in, [L,R]::out) is det :- split(X, 1, L, R)), Dirs, Spl), foldl2((pred([T, B]::in, D::in, Ds::out,

Your translation looks correct, and you might get a one-to-one translation with boxed arrays and table. J doesn't really encou

Although this does not seem like intended behaviour, it is worth mentioning that NuVoc explicitly states that _. is not recommended for use in J computations. On Fri, May 6, 2022 at 4:30 PM wrote: > Hello, > > > > _. does not mix well with lo
