https://codeforces.net/contest/1797/problem/C In this question I am getting wrong ans in test1 but it is working fine idk why I have tried the same type of problem https://codeforces.net/contest/1934/problem/C and it is working fine.
#define ll long long
#define pb push_back
#define vl vector<long long>
#define mll map<long long, long long>
#define pll pair<long long,long long>
#define mod 1000000007
#define fr(c,a,b) for(ll c=a;c<b;c++)
#include<bits/stdc++.h>
using namespace std;
ll query(ll x, ll y){
cout<<"? "<<x<<" "<<y<<endl;
ll z;cin>>z;
return z;
}
void solve()
{
ll n,m,a=0,b=0,c=0,d=0,l=0,s=0;cin>>n>>m;
ll x = query(1,1);
if(n<x+1){
a=n;b=x+2-n;
}else{
a=x+1;b=1;
}
ll y = query(a,b);
l = abs(a-y/2);
s=abs(b+y/2);
cout<<"! "<<l<<" "<<s<<endl;
}
int main()
{
ios_base::sync_with_stdio(false);cin.tie(0);cout.tie(0);
int t;cin>>t;
while(t--)
{
solve();
}
}
