Do you have in mind the good old TicTacToe?

Assuming that you get all the data in one array, you put a space around each value, `|` as a columns separator and multiple `-` as rows separator, with something like `["O", "X", " ", " ", "X", " ", "X", "O", " "]` you should be returning this structure (inclusive of new lines):

```
 O | X |   
-----------
   | X |   
-----------
 X | O |   
```

Now, to spice up things a bit, we are going to expand our board well beyond a trivial `3` x `3` square and we will accept rectangles of big sizes, still all as a long linear array.

For example, for `"O", "X", " ", " ", "X", " ", "X", "O", " ", "O"]` (same as above, just one extra `"O"`) and knowing that the length of each row is `5`, you will be returning

```
 O | X |   |   | X 
-------------------
   | X | O |   | O 
```

And worry not about missing elements, as the array/list/vector length is always going to be a multiple of the width.
