In "predecimalization" Britain, a British pound was divided into 20 shillings, and a shilling was divided into 12 pence ("pence" being their plural of "penny").

For lunch one day, Jack decides to have a steak and kidney pie and beer. Write a program to determine the change Jack will receive from having a pie and pint. Your program should ask for the amount of money that Jack has, and for the price of the pie, and the price of the beer, each in pounds/shillings/pence amounts. Output the pounds/shillings/pence change Jack will receive. Your output should report as many pounds as possible, less than 20 shillings and less than 12 pence. You may assume that input for shillings will be less than 20, and that input for pence will be less than 12. You may also assume that the cost of the lunch will not exceed the amount of money Jack has.

The following is a sample execution: Enter the pounds that Jack has: 4 

Enter the shillings that Jack has: 10 

Enter the pence that Jack has: 6 

Enter the pounds for the pie: 1 

Enter the shillings for the pie: 2 

Enter the pence for the pie: 3 

Enter the pounds for the beer: 1 

Enter the shillings for the beer: 12 

Enter the pence for the beer: 0
