As you might know, the answer to the ultimate question is 42, according to Douglas Adams`s famous book "Hitchhiker`s Guide to the Galaxy".

We do not need a supercomputer and millions of years to prove that. Whatever you specify as right argument to this function:

MeaningOfLife←{+.×/⍎⊖⍕⊃¨⊂|⌊-*+○⌈∨.∧/>\</×÷!⌽⍉⌹~⍴⍋⍒,⍟?⍳''≡1↑0⍴∊⍵}

...will produce THE answer, for example:

      MeaningOfLife 1  
42
      MeaningOfLife 'aaa' 
42
      MeaningOfLife¨10 4⍴2 (2 3) 'abcdef'
