A, B and C work together in a workshop. They produce 8, 10, and 12 products each day

respectively. Their performances are independent of each other. None of them work on Sunday. A

does not work on Tuesday. B does not work on Wednesday. C does not work on Monday and

Saturday. When a shipment of a certain amount of products is notified, you need to calculate when

you can deliver it.

Therefore, you write a program in which the inputs are the amount of products and the start date

as day of the week, and the output is how many days it will take to finish the shipment. The

shipment is finished when the cumulative amount of products produced on the last day is larger

than or equal to the target. Days of the week (i.e. start_date) correspond to the integers 0, 1, 2, 3,

4, 5, 6.

def shipment_date(product_amount, start_date):

# your logic here

# return how many days it take to finish

return total_days
