this code give run time error

Hello @khemchandrs,

There are multiple problems in your code:

  1. You have to write #include before using namespace std; else it will give error.

  2. You have not called the function sub_matrix_sum() inside main()

  3. The way you are assigning values to vector is incorrect.
    There are two ways of doing it:

    3.1.
    vector<vector > v;
    for(int i=0;i<n;i++){
    for(int j=0;j<m;j++){
    v[i].push_back(1);
    }}

    3.2.
    vector<vector > v;
    for(int i=0;i<n;i++){
    vector x;
    for(int j=0;j<m;j++){
    x.push_back(1);
    }
    v.push_back(x);
    }

Hope, this would help.
Give a like if you are satisfied.
