Write some python code that, given a variable n which contains a positive integer, generates a hollow right-angled triangle, as shown in the output below. Hint: The top and bottom of the triangle must be drawn separately, since they do not follow the same pattern as the lines between (spaces, then an asterisk, then spaces, and then another asterisk).
