For each of the challenges below, see if you can come up with two EXAMPLEs of how it should work!

1 Warping - Program one key to "warp" the player to a set location, such as the center of the screen.

examples: update-player​(​ ,  ,  ​) is   update-player​(​ ,  ,  ​) is   end

2 Boundaries - Change update-player such that PLAYER cannot move off the top or bottom of the screen.

examples: update-player​(​ ,  ,  ​) is   update-player​(​ ,  ,  ​) is   end

3 Wrapping - Add code to update-player such that when PLAYER moves to the top of the screen, it reappears at the bottom, and vice versa.

examples: update-player​(​ ,  ,  ​) is   update-player​(​ ,  ,  ​) is   end

4 Hiding - Add a key that will make PLAYER seem to disappear, and reappear when the same key is pressed again.

examples: update-player​(​ ,  ,  ​) is   update-player​(​ ,  ,  ​) is   end
