because in the test case 2, which offers a grid with size of 5x3 and the king is located in [5,1]. According to your codecout<<"? "<<1<<" "<<k+1<<endl;, it will output "? 1 5" where 5>3, so its illegal.

by the way, endl will flush the output automatically, so you dont need to write cout.flush(); again.
