A shopkeeper sells daily A units of item and his shop remains closed on weekends(Saturday and Sunday).
Find the number of weeks it will take to sell B units of item.
Assume first day to be Monday and return the ceil value of number of weeks. For eg: If it takes 9 days to sell all units then return 2 weeks.
1 <= A, B <= 109
First argument is an integer A dentoing the daily units sold by the shopkeeper.
Second argument is an integer B denoting the total units of item.
Return an integer denoting the required numbers of weeks.
A = 3 B = 17
A = 1 B = 1
On the first 5 days, shopkeeper can sell 15 units. On next 2 days shop remains closed(weekends). On 8th day sold remaining 2 units. Number of weeks will be 2.
On 1st day, shopkeeper can sell 1 unit. Nothing is remaining. Answer will be 1 week.
