Exercise 1.4.4 (Hard): Construct an explicit bijection from (0, 1] to (0, 1). Hint: One approach is as follows: First map (¹/2, 1] to (0,¹/2], then map (¹/4, ¹/2] to (¹/2, 3/4], etc. Write down the map explicitly, that is, write down an algorithm that tells you exactly what number goes where. Then prove that the map is a bijection.
