# Triple Double
#
# Have the function TripleDouble(num1,num2) take both parameters being passed, and return 1 if there is a straight triple of a number at any place in num1 and also a straight double of the same number in num2.

# For example: if num1 equals 451999277 and num2 equals 41177722899, then return 1 because in the first parameter you have the straight triple 999 and you have a straight double, 99, of the same number in the second parameter. If this isn't the case, return 0.

  tripleS = triple.to_s
