PImage mario; int count = 0; float timer; float delay = 90; float wakeupTime; void setup() { mario loadImage ("mario.jpg"); size (mario.width, mario.height); timer = 0; wakeupTime = delay; } void draw() { timer = timer + 1; if (timer >= wakeupTime) { } for (int y = 0; y < mario.height; y++) { for (int x = 0; x < mario.width; x++) { if (count % 2 == 0) { } } set(x, y, mario.get(x, y)); } else { } set (width-x-1, Y, mario.get(x, y)); count = count + 1; wakeupTime = wakeupTime + delay; 1. Describe the output of the above program. 2. Explain how this program flips the image. 3. Explain how is the variable timer is used. 4. Explain how is the variable wakeup Time is used.
