• The problem as stated is not completely defined, since it doesn't specify what to do if the word "sam" doesn't appear in the argument list. Here is a spec that addresses that question.

  countToSam One argument: A list of strings. Return: A non-negative integer, the number of elements up to and including the string "sam" in arg1. If the string "sam" does not occur in arg1, return 0.

  Example calls:

      countToSam(["i", "am", "sam.", "sam", "i", "am."]) --> 4
      countToSam(["i", "am", "sam", "sam", "i", "am"]) --> 3
      countToSam(["do", "you", "like", "green", "eggs", "and", "ham?"]) --> 0
      countToSam([]) --> 0
  

• Use iteration (e.g., a for loop, since we know how many times to repeat because of the list arg1) or recursion.
