    Do you actually know how to do "double transposition cipher" on paper?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Then (1) write down the steps you would do if you were doing it yourself (2) have the computer do each of those steps (3) done.
