Assignment #5 Pascal's Triangle

Use the following setup method (do not modify it in any way):

void setup() { int rows = getRows(); while (rows != 0) { printTriangle(rows); rows = getRows(); } }

In addition to the two above methods (printTriangle and getRows) you will need:
long nCr(int n, int r)
and
long factorial(int n)

To print a number so that it takes up a certain number of spaces you can use the method String.format from Java. Suppose a variable x has the value 15. To print it out so that it takes up 4 characters (2 spaces and then the 15) you would do:
print(String.format("%4d", x));
