Pascal Triangle

The below program is going to print the Pascal Triangle:

0 row = 1

1 row = adding the two numbers above them to the left and the right

         = (0+1) , (1+0)

         = 1 , 1

2 row = (0+1) , (1+1) , (1+0) 

          = 1 , 2 , 1

3 row = (0+1), (1+2), (2+1), (1+0)

          = 1 , 3 , 3 , 1

4 row = (0+1), (1+3)  , (3+3), (3+1), (1+0)

          =  1 , 4 , 6 , 4 , 1

 1

1        1

1      2       1

1      3       3      1 

1      4        6     4        1
