Code Craft: Driver Payment System

Here is the complete problem statement, examples, constraints, hints, and solution for the "Driver Payment System" interview question from Doordash on ShowOffer.io:

Problem Statement: DoorDash has a new driver payment system that calculates driver earnings based on the following rules:

1. Base pay: $30 per delivery.
2. Bonus: $10 per delivery if the delivery is completed within 30 minutes.
3. Surge pay: $5 per delivery if the delivery is completed during peak hours (6-8 PM).
4. Tip: Varies per delivery.

Write a function calculate_driver_earnings that takes in the following parameters:

• base_pay: Base pay per delivery (default = $30)
• bonus: Bonus per delivery if completed within 30 minutes (default = $10)
• surge_pay: Surge pay per delivery during peak hours (default = $5)
• delivery_time: Time taken to complete the delivery in minutes
• is_peak_hours: Boolean indicating if the delivery was completed during peak hours
• tip: Tip amount for the delivery

The function should return the total driver earnings, which is the sum of base pay, bonus, surge pay, and tip.

Examples:

1. calculate_driver_earnings(delivery_time=25, is_peak_hours=True, tip=5)

   • Base pay: $30
   • Bonus: $10 (since delivery time is within 30 minutes)
   • Surge pay: $5 (since delivery is during peak hours)
   • Tip: $5
   • Total earnings: $30 + $10 + $5 + $5 = $50

2. calculate_driver_earnings(delivery_time=45, is_peak_hours=False, tip=10)

   • Base pay: $30
   • Bonus: $0 (since delivery time is more than 30 minutes)
   • Surge pay: $0 (since delivery is not during peak hours)
   • Tip: $10
   • Total earnings: $30 + $0 + $0 + $10 = $40

Constraints:

• base_pay, bonus, surge_pay, and tip are non-negative numbers.
• delivery_time is a non-negative integer.
• is_peak_hours is a boolean value.

Hints:

• You can use conditional statements to check if the delivery time is within 30 minutes and if the delivery is during peak hours.
• Use the + operator to sum up the different components of the driver earnings.

Solution: `python def calculate_driver_earnings(base_pay=30, bonus=10, surge_pay=5, delivery_time=0, is_peak_hours=False, tip=0): total_earnings = base_pay + tip

if delivery_time <= 30:
    total_earnings += bonus

if is_peak_hours:
    total_earnings += surge_pay

return total_earnings

`

This function takes in the required parameters and calculates the total driver earnings based on the given rules. It uses conditional statements to check for bonus and surge pay eligibility and adds up the different components to get the final earnings.
