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 code
cout<<"? "<<1<<" "<<k+1<<endl;, it will output "? 1 5" where 5>3, so its illegal.by the way,
endlwill flush the output automatically, so you dont need to writecout.flush();again.but k will be 4 in that case,i think
sorry my bad, read the explaination again
Thanks, got accepted :) https://codeforces.com/contest/1797/submission/214048089
