I got WA 1. I think this problem is, easy but WA 1!!!

I was also getting WA on test case 1.The correct pattern for 7 is-

7
1 1 1 0 1 1 1
1 1 0 0 0 1 1
1 0 0 0 0 0 1
0 0 0 0 0 0 0
1 0 0 0 0 0 1
1 1 0 0 0 1 1
1 1 1 0 1 1 1

at first it seems -
7
1 1 1 0 1 1 1
1 0 0 0 0 0 1
1 0 0 0 0 0 1
0 0 0 0 0 0 0
1 0 0 0 0 0 1
1 0 0 0 0 0 1
1 1 1 0 1 1 1
