Question- Prove: Every decidable set is Turing reducible to the empty set.
Can anyone help me with this please?
All reductions tutorials I've seen use practical examples of reduction such as sipser's introduction to computation theory:
"A reduction is a way of converting one problem to another problem in such a way that a solution to the second problem can be used to solve the first problem. ... For example, suppose that you want to find your way around a new city. You know that doing so would be easy if you had a map. Thus, you can reduce the problem of finding your way around the city to the problem of obtaining a map of the city"
I don't see how to use this kind of information as a general proof, or how the empty set is even usable to solve anything else in a practical example even.
