Write a method that returns the sum of the desired numbers from the 'nums' array. Only use numbers that are in the same position in the 'nums' array as a value of TRUE in the 'include' array. For example, if 'nums' is {7,9,15,20,33} and 'include' is {true,false,false,true,false}, you would return 27 because 7+20=27 (since 7 and 20 were in the same position as a 'true' value in 'include'). Note: If the entire 'include' array contains 'true', you will return the sum of ALL the numbers in 'nums'. If the entire 'include array contains 'false', you will return a zero. Preconditions: 'nums' can contain any integers and can be any length, including a length of zero. The length of 'nums' and the length of 'include' are the same.
