(Processing Java Q) The following code is a very boring program it takes some kind of key number (in this case, 90210), and uses it to generate a unique scene. All the quantities, the colors, and the size and location of the ellipse, are generated based on this number. First, type the program into processing and get it working (try your phone number!). Then, fix the program using comments, good variable names, and named constants, to be more readable.

size(500,500);

int a = 90210;

int b = a%256;

int c = (a*13)%256;

int d = a%(500/2);

int e = a%500;

int f = (a*13)%500;

d = max(10, d);

e = max(0, e);

f = max(0, f);

background(b);

stroke(c); fill(c);

ellipse(e, f, d, d);
