In this exercise, we review a simple but very powerful mechanism that can be used to reduce the bias of a source of entropy. Suppose that you have access to a source of bits and you want to generate sequences of random bits. The problem is that the source is not perfect, 1s and 0s may be not equally distributed, and some patterns may be more
