Rocks are being dropped into bins in order until all the rocks are dropped into bins. For example, given 3 bins and 5 rocks, the first rock would be dropped into bin 1. Next the second rock would be dropped into bin 2. The third rock would be dropped into bin 3. Now we start over with the fourth rock getting dropped into bin 1. The fifth and final rock gets dropped into bin 2. What we want to know is: "What bin number does the last rock get dropped into?" In the example above, the last rock is dropped into bin 2, so we would return a 2. Write a method that returns which bin number the last rock is dropped into. Look at the test data for examples.
