Write a method that finds the "total" of an array of integers. The "total" is found by adding the elements of the array until a 37 is encountered. The 37 acts as a toggle, so after the first occurance of a 37, the next numbers are SUBTRACTED from the total until another 37 is encountered. Then it switches back to adding. Each occurance of a 37 toggles between adding and subtracting. The 37's are NOT counted in the total at all. For example, {5, 30, 37, 2, 1, 37, 20} would result in 52. That result was obtained by: 5+30-2-1+20. Look at the test data for additional examples.
