Agreed. For instance, how many possible integers are contained between each period in an IP address? I do not know of the top of my head.

I had this same issue in Python. This test is the issue: Test.assert_equals(race(820, 850, 550), [18, 20, 0]) My math (same as above math) calculates 59.99999999999574 seconds, which if stored with less precision would return 60 if converted to int. I think that test should just be removed or altered slightly so as to not produce an amount of seconds so close to 60.
