This problem needs more clarification

    1. If 12:9 is a valid input, why isn’t 2:2 a valid output? You are treating the input and output in different manners, which should really be formatted in the same way.

    2. If 12:9 is valid, do we need to convert it to 12:09 before processing so that 0 is a digit we can use? Or in this case we cannot use 0?
