Question 37

An algorithm is designed to determine electric vehicle (EV) charging rate categories based on the vehicle's battery capacity (in kWh), the day of the week (where 1 is Monday and 7 is Sunday), and the hour of the day (in 24-hour format).

3  IF (capacity < 20) OR (capacity >= 100) THEN
4      SEND "Specialist Rate" TO DISPLAY
5  ELSE
6      IF (day = 6) OR (day = 7) THEN
7          IF hour >= 18 THEN
8              SEND "Peak Weekend Rate" TO DISPLAY
9          ELSE
10             SEND "Standard Weekend Rate" TO DISPLAY
11         END IF
12     ELSE
13         IF (hour >= 7) AND (hour <= 10) THEN
14             SEND "Peak Weekday Rate" TO DISPLAY
15         ELSE
16             SEND "Off-Peak Weekday Rate" TO DISPLAY
17         END IF
18     END IF
19  END IF

Complete the table to show the output of the algorithm for each set of inputs.
