The Sierpinski triangle is a geometric figure that may be generated as follows: 1. Draw a triangle; 2. Draw a new triangle by connecting the midpoints of the three sides of your original triangle. This should split your triangle into four smaller triangles, one in the center and three around the outside. 3. Repeat step 2 for each of the outside triangles (not the center one). Each of them will split into four yet smaller triangles. Repeat for each of their outside triangles, and for each of the new ones... and so on. Create an application that draws the Sierpinski triangle. Your application should have GUI and allow users to choose how many times step 2 is performed.
