-*  Using the JavaScript language, have the function FirstFactorial(num) take the num   *
-*  parameter being passed and return the factorial of it (ie. if num = 4,              *
-*  return (4 * 3 * 2 * 1)). For the test cases, the range will be between 1 and 18.    *                                                     *
+*  Have the function AlphabetSoup(str) take the str string parameter being passed      *
+*  and return the string with the letters in alphabetical order                        *
+*  (ie. hello becomes ehllo). Assume numbers and punctuation symbols will not be       *
+*  included in the string.                                                             *

-*  You can either use an iterative or recursive function to solve this challenge.      *
-*  I am going to use an interative function. I am going to start with a value of 1     *
-*  for my total and then keep multiplying it by the next number until I reach num.     *
-*                                                                                      *
-*  This function needs to account for a possible outlier - One and Zero.               *
-*  If num is 1 or 0 then the answer is 1. By setting tot to value of 1 at              *
-*  initialization, then it guaranteees that 1 will be returned if num is ever 0 or 1.  *
+*  The Array has a built-in sort function but String does not. The first step is to    *
+*  convert the string to an Array and sort it in alphabetical order. Then covert the   *
+*  Array back to a string with the toString() function.  The last step is to remove    *
+*  the commans that separate each character.                                           *
 *  Steps for solution                                                                  *
-*    1) Set var tot to 1.                                                              *
-*    2) Loop from 2 to num and multiple tot by num to get new tot.                     *
-*    3) Return tot for answer.                                                         *
+*    1) Convert string to an array                                                     *
+*    2) Sort array in alphabetical order                                               *
+*    3) Convert array back to a string                                                 *
+*    4) Remove comma separators in our string                                          *
 *                                                                                      *
