数据是不是太弱？

#include<bits/stdc++.h>
using namespace std;
long long n,m,a[123][132];
string l;
int main(){
    scanf("%lld %lld",&n,&m);
    for(int i=0;i<n;i++){

        cin>>l;
        while(j<=l.size()-1){
            if(l[j]=='*')a[i][j]=-100000000;
            j++;
        }
    }
    for(int i=0;i<n;i++){
