    As of writing this, 181000ish completions of this kata, at almost 9 years old and after ALL of that scrutiny, a lone code wolf FINALLY cracked the secret, that the tests are wrong.

    I guess there are some errors in this test. even the description is wrong.

    39 --> 3 (because 39 = 27, 27 = 14, 1*4 = 4 and 4 has only one digit)
    how is 39 --> 3. it i should be 4 and it's even written up there

    Or did i misunderstand the test?
