Hi Can you help with this exercice. (I'm not allowed to modify neither the begining or the end of the program). I have a problem when the renting cost calculation is done using both rates. The rental rates are as follows:

From 00:00 to 07:00 and from 17:00 to 24:00: 1 Franc/hour;

From 07:00 to 17:00: 2 Francs/hour.
