It's not a "brain teaser" or a "trick question". It's an ordinary software engineering problem.

  Doing it on a whiteboard is an academic computer science problem. Doing it on a computer is more along the lines of a software engineering problem, though still it is largely academic and counter to one of the tenets of good software engineering (that all code is a liability, and thus new/non battle tested code should be avoided whenever possible).

    I wouldn't solve all car engine problems by completely replacing the engine, but if I was hiring a mechanic I'd want to verify he could replace the engine if needed.

      If you were hiring a mechanic, why would you test them on their ability to design engines?
