Write a method that returns the sum of all the numbers in array 'nums' but not including any numbers that match the value of 'excluded'. Array 'nums' can be any length, including length zero. Each number could be positive, negative, or zero. All numbers are included in the sum except 'excluded'. For example, if 'nums' is {5,7,3,1,10,2,7} and 'excluded' is 7, the sum would be 5+3+1+10+2 which is 21. Look at the test data for more examples.
