#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
typedef pair<int, int> PII;
typedef pair<double, double> PDD;
typedef unsigned long long ull;
void solve() {
int la, ra, lb, rb;
cin >> la >> ra >> lb >> rb;
if (ra - la + 1 >= 10 || rb - lb + 1 >= 10) {
cout << 9 << '\n';
} else {
int ans = 0;
for (int i = la; i <= ra; i++) {
for (int j = lb; j <= rb; j++) {
int x = i + j, res = 0;
while (x) {
ans = max(ans, x % 10);
x /= 10;
}
}
}
cout << ans << '\n';
}
}
int main() {
ios::sync_with_stdio(false);
cin.tie(nullptr);
int t = 1;
cin >> t;
while (t--) {
solve();
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
