Write a program to generate a triangle or an inverted triangle based upon user's choice of triangle to be displayed.

Example 1:
Input: Type 1 for a triangle
Enter your choice: 1
Sample Output:
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5

Example 2:
Input: Type 2 for an inverted triangle
Enter your choice: 2
Sample Output:
5 5 5 5 5
4 4 4 4
3 3 3
2 2
