Given a number N. The task is to print Floyd's triangle with N lines.
Example 1:
Input:
N = 4
Output:
1
2 3
4 5 6
7 8 9 10
Explanation:
For N = 4 there are 4 rows in the output
and the number of elements increases 
with an increase in the row.
 
Example 1:
Input:
N = 5
Output:
1
2 3
4 5 6
7 8 9 10
11 12 13 14 15
Explanation:
For N = 5 there are 5 rows in the output
and the number of elements increases 
with an increase in the row.
Your Task:  
You don't need to read input. Your task is to complete the function printFloydTriangle() which takes an integer N as input parameter and prints the triangle.
