WA 10. Give this test please...

Have trouble with this test too... and one question:
if input is like that:
7 6
1 2 3 4 5 6 7
should be output like that:
   1   3   4   5   6   7
   2
or that:
   1   3   5   7
   2   4   6

The answer is:

   1   3   5   7
   2   4   6

Remember about the correct number of spaces.

My AC program show :
1 3 4 5 6 7
2

it is incorrect answer or test
>the columns have the same height with the possible exception of the last column, which may be shorter

This test is incorrect. Timus Online Judje Team likes give people incorrect tests.
