Adyen Kotlin Assignment

This repository contains the coding assignment for candidates applying for a Kotlin Engineer role at Adyen. The goal of the assignment is to implement a cash register.

Criteria:

• The CashRegister gets initialized with some Change.
• When performing a transaction, it either returns a Change object or fails with a TransactionException.
• The CashRegister keeps track of the Change that's in it.

Bonus points:

• The cash register returns the minimal amount of change (i.e. the minimal amount of coins / bills).

Feel free to make any changes to the code in the assignment. As part of the zip file you received is the local Git repository, you can use that to show us your development and thought process in the commit history.
