- You are building a checkout system for a shop which only sells apples and oranges.
- Apples cost 60p and oranges cost 25p.
- Build a checkout system which takes a list of items scanned at the till and outputs the total cost
- For example: [ Apple, Apple, Orange, Apple ] => £2.05
- Make reasonable assumptions about the inputs to your solution; for example, many candidates take a list of strings as input
- The shop decides to introduce two new offers
- buy one, get one free on Apples
- 3 for the price of 2 on Oranges
- Update your checkout functions accordingly
