When the set in a Sudoku cell contains only one element, this means that the digit at that cell is known. We can then propagate the knowledge, ruling out that digit in the same row, in the same column, and in the same 3x3 block. For this problem, you will write a method that propagates the constraint from a single cell. The method will return the list of newly-determined cells, that is, the list of cells who also now (but not before) are associated with a 1-element set. This is useful, because we can then propagate the constraints from those cells in turn. Further, if an empty set is ever generated, we raise the exception Unsolvable: this means that there is no solution to the proposed Sudoku puzzle.

Draw the hierarchy chart and design the logic for a program that calculates service charges for hazel's housecleaning service. the program contains housekeeping, detail loop, and end-of-job modules. the main program declares any needed global variables and constants and calls the other modules. the housekeeping module displays a prompt for and accepts a customer's last name. while the user does not enter for the name, the detail loop accepts the number of bathrooms and the number of other rooms to be cleaned. the service charge is computed as $40 plus $15 for each bathroom and $10 for each of the other rooms. the detail loop also displays the service charge and then prompts the user for the next customer's name. the end-of-job module, which executes after the user enters the sentinel value for the name, displays a message that indicates the program is complete.
