# Matrix
Given a string representing a matrix of numbers, return the rows and columns of
that matrix.
So given a string with embedded newlines like:
```text
9 8 7
5 3 2
6 6 7
```
representing this matrix:
```text
0 1 2
|---------
0 | 9 8 7
1 | 5 3 2
2 | 6 6 7
```
your code should be able to spit out:
- A list of the rows, reading each row left-to-right while moving
top-to-bottom across the rows,
- A list of the columns, reading each column top-to-bottom while moving
from left-to-right.
The rows for our example matrix:
- 9, 8, 7
- 5, 3, 2
- 6, 6, 7
And its columns:
- 9, 5, 6
- 8, 3, 6
- 7, 2, 7
## Running tests
Execute the tests with:
```bash
$ elixir matrix_test.exs
```
### Pending tests
In the test suites, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
commenting out the relevant `@tag :pending` with a `#` symbol.
For example:
```elixir
# @tag :pending
test "shouting" do
assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
end
```
Or, you can enable all the tests by commenting out the
`ExUnit.configure` line in the test suite.
```elixir
# ExUnit.configure exclude: :pending, trace: true
```
