Here is the problem, "Write a procedure that takes in a string of 'B' and 'G' characters.  The procedure should rearrange the letters into an alternating 'B'-'G' pattern that continues until the less numerous letter runs out.  Assume the string only contains 'B's and 'G's; that the patter you create always starts with a 'B'; and that the string will always contain at least 1 of each letter.  For example: "BBBBGGGBG" becomes "BGBGBGBGB", and "GGBG" becomes "BGGG"."
