Would it make sense to change the params for the solutions to take a string rather than an array? I was thrown off by the use of sort in the second solution until I realized the "str" variable was actually an array.
The problem in the book clearly requests an implementation of an algorithm that works on a string. I suppose this is something the candidate could/should check before hand so I can understand reasoning for leaving it in.
