Bessie taught the cows to make Parkside's Triangle. It is generated from two numbers: the size and the seed. The size N (1 <= N <= 20) determines how many rows are in the triangle and the seed S (1 <= S <= 9) determines the first number in the triangle. Here are two examples:
N=5, S=3 N=6, S=1The first line of any triangle has no blanks at its front.
