i was solving this problem and i did this
#include
using namespace std;
int main(){
int t;
cin>>t;
while(t–){
int N,K;
cin>>N>>K;
int A[K];
for(int i=0;i<K;i++){
cin>>A[i];
}
while(N–){
int sum=0;
string S;
cin>>S;
for(int i=0;i<K;i++){
if(S[i]==‘1’)
sum=sum+A[i];
}
cout<<sum<<endl;
}
}
return 0;
}
