# Create a method same_number? that takes a string of x's and o's and determines
# if there are the same number of x's as o's. "xooxxxxooxo" has more x's and 
# therefore would return false. "xxooxxooxoxo" has the same amount of x's and o's,
# therefore would return true.

same_number?("xooxxxxooxooo")
