If I have a 2D vector like this that has 5000 elements declared.
If I have filled 2500 of these elements with Numbers, what is the best way if
I want to "emty" these elements so these elements will turn to 0 wich I beleive is the defaultvalue for all elements before I started to fill them ?
Is a for loop the best way to do it while putting all elements to zero (0).
std::vector<std::vector<int> > Numbers(5000, std::vector<int>(5000));
