# Transpose

Given an input text output it transposed.

Roughly explained, the transpose of a matrix:

```
ABC
DEF
```

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:

- Pad to the left with spaces.
- Don't pad to the right.

Therefore, transposing this matrix:

```
ABC
DE
```

results in:

```
AD
BE
C
```

And transposing:

```
AB
DEF
```

results in:

```
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).

## Setup

There are two different methods of getting set up to run the tests with Objective-C:

- Create an Xcode project with a test target which will run the tests.
- Use the ruby gem `objc` as a test runner utility.

Both are described in more detail here: http://exercism.io/languages/objective-c


### Submitting Exercises

When submitting an exercise, make sure your solution file is in the same directory as the test code.

For example, if you're submitting `Bob.m` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m`.
