P.S. The first test case isn't the sample.

Can you show me any possible solution sample input #2?

Incorrect test 55 was fixed. 5 authors got AC now. We apologize for jury error to all authors, especially to LouTianCheng and Team of Jyonh, who submitted correct solution during online contest.

Is this test correct? I think that my program is right.

Dear author, are you sure that answer ("NO") for the 1st example of input/output (
2 4
0 0 0
1 2 1
2 1 2
3 3 3
)
really correct?

Is it true that filling square as
0    1    3    2
2    3    1    0
3    2    0    1
1    0    2    3
is NOT correct magic square according to task rules?
