Return true if the given non-negative Int is 1 or 2 less than a multiple of 20. So for example 38 and 39 return true, but 40 returns false.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Kotlin's assert or check methods
