The Cantor diagonal construction is an algorithm for computing an
incomputable number.
Can you prove that it computes an incomputable number?
It’s trying to come up with a number that cannot fit into a set with
cardinality ℵ₀. The cardinality of the computable numbers is the same as
that of the integers, which is ℵ₀.
