Π01 class is a subset of 2ω

Step-by-step explanation:

The set 2<ω consists of all finite sequences of 0s and 1s, while the set 2ω consists of all infinite sequences of 0s and 1s (that is, functions from ω = {0, 1, 2,} to the set {0,1}).

A tree on 2ω is a subset of 2ω that is closed under taking initial segments. An element f of 2ω is a path through a tree T on 2ω if every finite initial segment off is in T.

answer: c i think

step-by-step explanation:
