```cpp
#include <bits/stdc++.h>
using namespace std;
const int maxn = 1e3+5;
int a[maxn];
int main(){
int n,m;
cin >> n >> m;
for (int i = 1;i <= n;i++){
cin >> a[i];
}
int x,y;
for (int i = 1;i <= m;i++){
int minn = INT_MAX;
cin >> x >> y;
for (int j = 1;j <= n;j++){
if ((a[j]-y)%(int)pow(10,x)==0 && (a[j]-y) >= 0){
minn = min(minn,a[j]);
}
}
if (minn == INT_MAX)
cout << -1 << endl;
else
cout << minn << endl;
}
return 0;
}
```
