I got WA on test17. I can't find my mistakes....
I think the sample test is incorrect.
My solution got the answer is :
2 2 -1 2 -1
3 2 2 7 2
1 8 7 5 7
1 6 5 -1 5
-1 1 4 -1 4
But the sample output is :
2 2 -1 2 -1
3 2 2 7 2
1 7 7 5 7
1 5 5 -1 5
-1 1 4 -1 4
I think the sample output is wrong , isn't it ???
Is my answer right ?
Who can tell me ????
