● 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
