Write a function that takes parameters r1  , r2  , n  and generates random points (x1,x2)  as follows -

• n  random points that lie within a circle with center at (0,0)  and radius r1  →  These points belong to class 'inner'
• n  random points that lie outside circle with center at (0,0)  and radius r1  but inside circle with center at (0,0)  and radius r2  →  These points belong to class 'outer'

The function gen_random should return X  , Cls  :

• X  is a numpy array of shape (2n,2)  which has the 2n  random points generated as above.
• Cls  is a numpy array of shape (2n,)  which contains the value of the class corresponding to each point in X  (values will be either 'inner' or 'outer')
