Here is Operator Overloading solution in c++ - https://programmingoneonone.com/hackerrank-operator-overloading-solution-in-cpp.html

This problem sucks. The prompt says that it will handle the IO but it doesn't and you have to write it yourself. Also, it doesn't specify what to do when T > 1 or how to format your answer. I just randomly guessed and it wanted one \n between each matrix.

Operator Overloading is a feature in object-oriented programming (OOP) that allows you to redefine the way operators work for user-defined data types. This means you can specify how operators like +, -, *, ==, etc., behave when applied to objects of a class. If you want more details then visit King Exchange.

Spot on! Operator overloading is a fantastic tool for boosting code readability and ease of use, letting custom types blend naturally with standard operators. It really shines when you’re dealing with intricate data structures, making the code feel more instinctive. Want to dive deeper into how Lord Exchange that connects to operator overloading?

Hope this helps for easy solution and better understanding:

class Matrix{
    public: 
        vector<vector<int>> a;
        
        Matrix operator +(const Matrix& b){
            int n = a.size();
            int m = a[0].size();
            Matrix result;
            result.a.resize(n, vector<int>(m, 0)); // 2D vector mxn with entries=0
            
            for(int i=0; i<n; i++){
                for (int j=0; j<m; j++){
                    result.a[i][j] = a[i][j] + b.a[i][j];
                }
            }
            return result;
        }     
};
