Write a method that returns the sum of all the integers in the array 'toAdd', unless 'dbl' is true. If 'dbl' is true, ODD numbers count normally towards the sum, but EVEN numbers count double. For example, if the array contains [5, 6, 4] and 'dbl' is false, you would return 15 since 5+6+4=15. However, if 'dbl' was true you would return 25 since 5+2*6+2*4=25. As a precondition, you may assume that the array will not contain any negative numbers. Look at the test data for additional examples.
