    IS This Wrong ? ** **I calculated first all sides area and then substrating accordingli ?

    int surfaceArea(int A_rows, int A_columns, int** A) {
    
    int area =6*A_rows*A_columns;
    int min = A_rows < A_columns ?  A_rows : A_columns;
     for (int i =0; i<A_rows;i++) {
          for (int j =0; j<A_columns;j++){
              area -= min - A[i][j];
          }
    
    }
    
    for (int i =0;i<A_columns;i++) {
        area -= min - A[0][i];
    
    }
    
     for (int i =0;i<A_columns;i++) {
        area -= min - A[A_rows-1][i];
    
    }
    
     for (int i =0;i<A_rows;i++) {
        area -= min - A[i][0];
    
    }
    
     for (int i =0;i<A_rows;i++) {
        area -= min - A[i][A_columns-1];
    
    }
    
    for (int i =0; i<A_rows;i++) {
        for (int j=0; j<A_columns;j++) {
            area = area + min - A[0][0] + min - A[A_rows-1][A_columns-1]  + min- A[0][A_columns-1] + min -  A[A_rows-1][0];
        
        }
    
    }
    if(A_columns == 1 &&  A_rows == 1 )
    {
        return area;
    }
    return area-1;

}
