Matrix

Write a program that, given a string representing a matrix of numbers, can return the rows and columns of that matrix.

So given a string with embedded newlines like:

9 8 7 5 3 2 6 6 7

representing this matrix:

    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

To run the tests simply run the command go test in the exercise directory.

If the test suite contains benchmarks, you can run these with the -bench flag:

go test -bench .
