java Integer variables totalMonth and inventory are read from input. Complete purchases$()\text{'}$s recursive case:

If month is odd, call purchases$()$ to compute the next month's inventory as the current month's inventory minus $5.$

Otherwise, call purchases$()$ to compute the next month's inventory as the current month's inventory minus $18.$

Ex: If the input is $5290,$ then the output is:

Month: $5,$ inventory: $244$

Note: x $\%2!=0$ returns true if x is odd.
