    In C++:

    int diagonalDifference(vector> arr) { int n; n = end(arr)-begin(arr);// Find the lenght of the array.

    cout << "n:" << n << endl; // error checking
    
    //Declaration of sum variables
    int sum_rtl =0;
    int sum_ltr =0;
    
    // Add up Left-to-Right
    for(int i = 0; i < n; i++ )
    {
        for(int j = 0; j < n; j++)
        {
            cout << "Before Sum LTR: " << arr[i][j] << endl;
            sum_ltr = sum_ltr + arr[i][j];
            i++;   
        }
        cout << "sum_ltr:"<<sum_ltr << endl;
    }
    //Add up Right-toLeft
    for( int i = 0; i < n; i++)
    {
        for(int j = n-1; j >= 0; j--)
        {
            cout << "Before Sum RTL: " << arr[i][j] << endl;
            sum_rtl = sum_rtl + arr[i][j];
            i++;    
        }    
        cout << "sum_rtl: " << sum_rtl << endl;
    }
    //Absolute value of the difference.
    int diff = abs(sum_rtl - sum_ltr);
    
    return diff;
    

    }

    The "Diagonal Difference" problem involves calculating the absolute difference between the sums of the two diagonals in a square matrix. The primary diagonal consists of elements where the row and column indices are equal, while the secondary diagonal consists of elements where the sum of the row and column indices equals n−1. To solve this, you can iterate through the matrix in website coding, summing the elements of both diagonals, and then return the absolute difference between the two sums.

    Diagonal Difference is a common algorithmic problem that involves calculating the absolute difference between the sums of a square matrix's primary and secondary diagonals. It is widely used to understand matrix manipulation in programming. For an engaging gaming experience, explore Null's Brawl Indir.
