I looked at the lectures and a couple of examples didn't really help.
I know that I need to start with the search for specific points.

Lightbulb

Now this example is interesting. Draw a contour with a center on the x-axis at the point z = 1 and a radius r = 1/2 and singular points: z = 0, z = + - 2i, which are outside the contour. There are no special points inside the contour, so the answer is the simplest = 0.
