Design a function f such that:
f(f(x)) == 1/x
Where x is a 32 bit float
Or how about
Given a function f, find a function g such that
f(x) == g(g(x))
Design a function f such that: f(f(x)) == 1/x Where x is a 32

For the first part: this one is more trivial than f(f(x)) = -x, IMO:
The second part is an interesting question and an obvious generalization of the original question that this question was based on. There are two basic approaches:
