<strong>Floyd's Triangle                </strong><strong>Reverse of Floyd's Triangle</strong>

Accept the number of rows to print the Floyd’s Triangle
Print value 1 for the Row 1
Print two values 2 and 3 in the next row
Print three values 4, 5 and 6 in the next row
Repeat till the number of rows specified

Accept the number of rows to print the reverse of Floyd’s Triangle
Print the values in the reverse order as specified in the reverse of Floyd’s Triangle
