Write a method that returns the product of all the integers from 'low' to 'high' inclusive. For example if 'low' is 3 and 'high' is 5, the product of all the integers from 3 to 5 is 3*4*5=60. You may assume that 'high' is greater than 'low' and that the result will be less than the maximum possible Java integer. You may also assume that 'low' is at least 1.
