F#: let f = function | 0 , 0 , 0 -> 0 | 0 , 1 , 1 -> 0 | 1 , 0 , 1 -> 0 | 1 , 1 , 0 -> 0 | _ -> 1
for a in 0..1 do for b in 0..1 do for c in 0..1 do printfn "%i xor %i xor %i = %i" a b c (f (a, b, c)) Output: 0 xor 0 xor 0 = 0 0 xor 0 xor 1 = 1 0 xor 1 xor 0 = 1 0 xor 1 xor 1 = 0 1 xor 0 xor 0 = 1 1 xor 0 xor 1 = 0 1 xor 1 xor 0 = 0 1 xor 1 xor 1 = 1This man again took advantage of the fact that in D there is no such operation -> (analog switch).
