Endpoints

• POST /receipts/process: Accepts a receipt JSON, calculates points, and returns a unique receipt ID.
• GET /receipts/{id}/points: Retrieves the points for the receipt with the specified ID.

Rules for Points Calculation

• Retailer Name
  • One point for every alphanumeric character in the retailer name.
• Total Amount
  • 50 points if the total is a round dollar amount with no cents.
  • 25 points if the total is a multiple of 0.25.
• Item Count
  • 5 points for every two items on the receipt.
• Item Description Length
  • If the trimmed length of the item description is a multiple of 3, multiply the price by 0.2 and round up to the nearest integer. The result is the number of points earned.
• Purchase Date and Time
  • 6 points if the day in the purchase date is odd.
  • 10 points if the time of purchase is after 2:00pm and before 4:00pm.
