Challenge Optical illusion

Complete the circle drawing functions



In this challenge you will make a cool-looking optical illusion! The illusion
will use overlapping black and white circles.

The function drawWhiteCircle should draw a white circle, and the function drawBlackCircle
should draw a black circle. The circles drawn by the functions should have their centers
at (0,0). Both of the functions should use the input parameter named diameter to control
the diameter of the circles that are drawn.

Var drawWhiteCircle = function(diameter) {

Fill(----, ----, ---- 0;

Ellipse(0, 0, ----, ----);

};

Var drawBlackCircle = function(diameter) {

Fill(----, ----, ---- 0;

Ellipse(0, 0, ----, ----);

};
