Transpose

Given an input text output it transposed.

Roughly explained, the transpose of a matrix:

1
2
ABC
DEF

is given by:

1
2
3
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:

1
2
ABC
DE

results in:

1
2
3
AD
BE
C

And transposing:

1
2
AB
DEF

results in:

1
2
3
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).
