Frank is a contractor. His company has been brought in to refactor some back-end web services that were all developed by a single person, "Nicholas," over the course of a couple of years.

From the front lines,

Having looked at it, we've decided that a complete rewrite is the only solution. Here's just one example of what can only be called "paid by the line" programming.

private int GetMessage( int selected ) { int index = 0; // Get the Message switch( selected ) { case 0: index = 0; break; case 1: index = 1; break; case 2: index = 2; break; case 3: index = 3; break; } return index; }

According to the submission, we can "only imagine what other fun things this codebase does" but I can't think of anything. Instead, the challenge of the day is to rewrite this function as many different ways as possible. Keep in mind, you're not being paid by the line.
