#include <iostream>

#include <cstring>
#include <algorithm>
using namespace std;
typedef long long ll;
const int N = 1e5 + 100;
const int MOD = 998244353;
int getmax(int x){
int maxn=0;
while(x){
maxn=max(maxn,x%10);
x=x/10;
}
return maxn;
}
void sol() {
int la,ra,lb,rb;
cin>>la>>ra>>lb>>rb;
if(ra-la>=10||rb-lb>=10)

cout<<9<<endl;
return;
}
int maxn=0;
for(int i=la;i<=ra;i++){
for(int j=lb;j<=rb;j++){
maxn=max(maxn,getmax(i+j));
}
}
cout<<maxn<<endl;
}
int main() {
ios::sync_with_stdio(0);
cin.tie(0);
cout.tie(0);
int T = 1;
cin >> T;
while (T--) {
sol();
}
exit(0);
}
这程序好像有点Bug,我给组数据试试?
