                    You are in charge of decorating your school’s Annual Day event with a limited

                    budget. To ensure efficient use of resources, make a list of supplies with their
                    quantities and calculate the total cost. Convert the total price into binary and
                    count  the  number  of  digits.  Compare  whether  there  are  more  digits  in  the
                    decimal or binary representation.
