Joe Warren: 4 Ways to Make Change in Scala

Come along to another London Scala Talk where we hear from Joe Warren on functional programming techniques and how to learn them.

Joe Warren: 4 Ways to Make Change in Scala
Given a fixed sum of money, what's the smallest number of coins that add up to it?

This is an example of the kind of problem you might solve as part of a coding kata; a well defined problem used to practice programming.
In this talk, we'll look at a number of different solutions to the change making problem, and ask:

• Is this a good way to teach programming?
• What are the pros and cons of different programming styles?
• Will I ever be able to sell my colleagues on the joys of functional programming?
• And what are recursion schemes, and why should we care?
