Please complete the coding exercise.

Write a simple application that given a number of pennies will calculate the minimum number of Sterling coins needed to make that amount.

Eg. 123p = 1 x £1, 1 x 20p, 1 x 2p, 1 x 1p

• Account for only the common £2, £1, 50p, 20p, 10p, 5p, 2p and 1p coins. Ignore those commemorative £5 coins
• You should use Scala or Java to do this
• The method should accepts an 'amount' string (Eg. 92p, £2.12) or integer and returns the denominations needed

• Test Driven Development
• Performance
• Maintainability

• Writing the code in a modular way, implementing separation of concerns (presentation layer, business logic layer, etc)
• Verbalising how you're approaching and solving the problem and breaking it down as you're coding
• High quality and maintainable code
• Use of test driven development and writing new unit tests
• Well documented and commented code
• Follow coding standards
