Let's have an algorithm that starts with
0.1 in binary, and constructs a tree in breadth-first fashion
0.1
0.01 0.11
0.001 0.011....
You get the idea... It's obvious that this tree has the same
cardinality as Z, since this is a nonhalting algorithm (or since I can
give an integer to every node, etc.) Now, I want to prove that such a
subdivision procedure cannot generate all x in (0,1) in an intuitive
way. Is the easiest method proof by contradiction?
