The difference between Period units

Report a typo

Find and subtract the smallest Period unit from the sum of all units using the minus() method. Note that you need to implement the getSumMinusMin() method to return the result of the subtraction but this doesn't mean that all logic must be there. You can have more methods. Use the calculateDayCount() method to calculate the number of days in a year for comparison.
