Suppose that inside the main method below you decide to create a Scanner object, and then read in an int and then a double on one line, where the two values are separated by a space, e.g.
19 3.7778

Complete the main method below for doing this chore. Notice that we've constructed a Scanner object for you - be sure to use this object. You should store the integer in an int variable called n, and the double value in a double variable called r. Finally, in the last statement in main, you should print the sum of these two values.
