Complete the code which generates the following pattern (Note: the solution uses lines, although it would also be possible to create the image using rotated rectangles, which is covered in Chapter 14).
void setup() {
size(400,200);
smooth();
}
void draw() {
background(255);
stroke(0);
branch(width/2,height,100);
}
void branch(float x, float y, float h) {
________________________________________;

if (__________________) {

}
}

}
}
Finally, I have to understand the code by a stupid way (draw each points then connect them on paper), and I think it’s obviously not an advanced way of thinking, so, could you please show me a smarter way of thinking the code above? Thank you.
