2.Using the top–down method, please describe an algorithm for a program that calculates the cost of a car rental according to the following price schedule:The algorithm asks the user to enter the rental period and type of car. The algorithm should display the appropriate cost. If a period longer than 60 days is entered, a message "Rental is not available for more than 60 days" should be displayed. If a rental period of less than 6 days is entered for Class D, a message "Class D cars cannot be rented for less than 6 days" should be displayed. Create a flowchart for your algorithm.
