The problem as stated does not have a unique solution in general, as you’ve found. One Julia program for this is `sort(split(p)[count.(r"[aeiou]", split(p)) .< 3]; by=r -> length(r))[end]` which also returns "grasp". But this one appeals to me more, because it doesn’t split twice: `sort(filter(w -> count(r"[aeiou]", w) < 3, split(p)); by=r -> length(r))[end]`
