# Change

Correctly determine the fewest number of coins to be given to a customer such
that the sum of the coins' value would equal the correct amount of change.

## For example

- An input of 15 with [1, 5, 10, 25, 100] should return one nickel (5)
  and one dime (10) or [0, 1, 1, 0, 0]
- An input of 40 with [1, 5, 10, 25, 100] should return one nickel (5)
  and one dime (10) and one quarter (25) or [0, 1, 1, 1, 0]

## Edge cases

- Does your algorithm work for any given set of coins?
- Can you ask for negative change?
- Can you ask for a change value smaller than the smallest coin value?

The Scala exercises assume an SBT project scheme. The exercise solution source
should be placed within the exercise directory/src/main/scala. The exercise
unit tests can be found within the exercise directory/src/test/scala.

To run the tests simply run the command `sbt test` in the exercise directory.

For more detailed info about the Scala track see the [help
page](http://exercism.io/languages/scala).
