Given a string representing a matrix of numbers, return the rows and columns of that matrix.

So given a string with embedded newlines like:

representing this matrix:

1
2
3
4
5
    0  1  2
  |---------
0 | 9  8  7
1 | 5  3  2
2 | 6  6  7

your code should be able to spit out:

The rows for our example matrix:

And its columns:

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.
