太简单了

#include<iostream>
using namespace std;
int main(){
int n,m;
cin>>n>>m;
int a[n][m],b[n][m];
for (int i=0;i<n;i++){
for (int j=0;j<m;j++){
cin>>a[i][j];
}
}
for (int i=0;i<n;i++){
for (int j=0;j<m;j++){
cin>>b[i][j];
}
}
for (int i=0;i<n;i++){
for (int j=0;j<m;j++){
cout<<a[i][j]+b[i][j]<<" ";
}
cout<<endl;
}
return 0;
}//太简单了
