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 .
