/* Problem: Print out a grid of numbers that looks like this: 
                    row     col     no_of_rows
1                    1       1          1 
1 2                  2       2          2  
1 2 3                3       3          3  
1 2 3 4              4       4
1 2 3 4 5            5       5   
    
So we are printing out a half a square...
