vector subscript out of range during compiling

You never add any elements to normal before trying to use normal[i].

You haven't put anything into normal. It sits as an empty vector until you put something into it.

You can fix this problem by giving it a new value each iteration

for (i = 0; i < 10; i++) {
    normal.push_back(vector<int>());
    for (j = 0; j < 10; j++) {
         normal[i].push_back(j);
    }
}

Also, your i and j were being initialized to 1, but I'm fairly certain you meant 0. I addressed this in my snippet.

Vector normal is empty. You can initialize vector as follow.

vector<vector<int>> normal(10, vector<int>());
