Snowball Rolling Down a Mountain
Problem Statement:
The pre-placed block has x, y and radius values that place the snowball at the top of the mountain. Adjust the values so that the snowball will move in a diagonal direction down the mountain.

#include <chplot.h>

plot.strokeColor("black");
plot.strokeWidth(1);
plot.fillColor("#cccccc");
plot.triangle(0, 18, 0, 0, 18, 0);
