Given an input text output it transposed.
Roughly explained, the transpose of a matrix:
is given by:
AD BE CF
Rows become columns and columns become rows. See https://en.wikipedia.org/wiki/Transpose.
If the input has rows of different lengths, this is to be solved as follows:
Therefore, transposing this matrix:
AD BE C
AD BE F
In general, all characters from the input should also be present in the transposed output. That means that if a column in the input text contains only spaces on its bottom-most row(s), the corresponding output row should contain the spaces in its right-most column(s).
make chez if you're using ChezScheme or
make guile if you're using GNU Guile.
Sometimes the name for the scheme binary on your system will differ from the defaults.
When this is the case, you'll need to tell make by running
make chez chez=your-chez-binary or
make guile guile=your-guile-binary.

(test)to check your solution.
If some of the test cases fail, you should see the failing input and the expected output.
The failing input is presented as a list because the tests call your solution by
(apply transpose input-list).
