Imagine a square tile with four numbers on it, one on each edge. We will call these edges north, east, south, and west.If the four numbers were [1 5 7 9], this vector would be displayed with the numbers going around clockwise from the north like so:<pre> 1 
 9 5
 7 </pre>But the tile can appear in four different orientations. Let's say that when the north is 1, then the first number appears in the north position. If north is 2, then the second number appears in the north position, and so on.

 5 9
 1 </pre>The numbers you are given will always be one or two digit positive integers. You must return a 3-by-6 character array that fits this template:<pre class="language-matlab">..NN..

</pre>where dots are used to indicate spaces (ASCII 32). One digit numbers should be right aligned. In the example given immediately above, the output should look like this:<pre> Inputs t = [1 5 7 9], north = 3
 Output is [' 7 '

 ' 1 ']</pre>

Imagine a square tile with four numbers on it, one on each edge. We will call these edges north, east, south, and west.

If the four numbers were [1 5 7 9], this vector would be displayed with the numbers going around clockwise from the north like so:

1  
  9   5
    7

But the tile can appear in four different orientations. Let's say that when the north is 1, then the first number appears in the north position. If north is 2, then the second number appears in the north position, and so on. So if the tile numbers are [1 5 7 9] and the orientation parameter north is 3, then it would display like so, since 7 is the third number:

7  
  5   9
    1

The numbers you are given will always be one or two digit positive integers. You must return a 3-by-6 character array that fits this template:

..NN..
  WW..EE
  ..SS..

where dots are used to indicate spaces (ASCII 32). One digit numbers should be right aligned. In the example given immediately above, the output should look like this:

Inputs t = [1 5 7 9], north = 3
 Output is  ['   7  '
             ' 5   9'
             '   1  ']

I might have misunderstood the statement, but to me the second test is wrong and td should be defined by
td = [' 8 '
' 5 27'
' 46 '];

Alfonso Nieto-Castanon on 2 Mar 2013

I believe the test is correct; if north is 4 then the fourth number (46 for test 2) should appear in the north position (not 8, which is the second number)

Cedric Wannaz on 4 Mar 2013

Ah! I misunderstood the question then; I thought that there was a rotation in directions according to the north parameter, whereas the latter indicates which of the four numbers should be placed in the north position.
