The code defines a function that will return the position of the mouse in relation to the points (x, y) and (z), according to the following rules:
If the mouse is above or to the left of (x, y), it will return "Mouse C";
If the mouse is below or to the right of (x, y), it will return "Cat A";
Otherwise, it will return the position of the cat in relation to (x, y).
function catAndMouse(x, y, z) {
let catAPos = Math.abs(z - x);
let catBPos = Math.abs(z - y);
if (catAPos < catBPos) {
return "Cat A";
} else if (catBPos < catAPos) {
return "Cat B";
} else {
return "Mouse C";
}
}
