                     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.
