Question

How many squares are drawn if foo(0,0,5,1) is called?

Assume that the function drawSquare(double x, double y, double halfLen) draws a square with
a side length that is double of halfLen, centered at (x, y). For example, drawSquare(0,0,5) draws
a square centered at (0,0) with each side of length 10.
Consider the following function foo defined as:
public static void foo(double x, double y, double len, int n) {
if (n < 1) return;
drawSquare (x, y, len);
foo(x-len/2, y-len/2, len/2,n-1);
foo(x-len/2, y+len/2, len/2,n-1);
foo(x+len/2, y+len/2, len/2,n-1);
foo(x+len/2, y-len/2, len/2,n-1);
}
