Coding Exercise 7

Prerequisite Concepts	7, 12
Key Concept	19

Using only the Level 4 functions sphere and put, create a function called sphericalWedge that, when called with the following actual parameters

sphericalWedge 12 BLUE ORANGE RED (12,12,12);

creates the artifact shown in Figure 1. In your function, the center of the sphere should be created by the function call:

put (3,3,3) BLACK (x-1,y-1,z-1);

The wedge is to be created through three put function calls, each of which create a rectangular prism consisting of EMPTY bricks. Each “put” should slice away half of the sphere. The part removed should include the point (x,y,z). Note that the order in which “put” function calls are executed is irrelevant. The final result will always be the same and will include exactly 1 black bit-brick.
