Write a method that returns the sum of all the integers from 'low' up to and including 'high', except do NOT include 'exclude' or any multiple of 'exclude'. As preconditions you may assume that 'low' is less than or equal to 'high' and that the sum will not exceed the maximum value that can be stored in an integer. You may also assume that all three parameters are positive numbers. For example, if 'low' is 2, 'high' is 7, and 'exclude' is 3 you would return an 18 since 2+4+5+7 = 18. (Note that 3 and 6 were NOT included in the sum since they are multiples of 3). Look at the test data for other examples.
