$Given a language L subsetorequal {0, 1}^* such that L intersection$

Given a language L subsetorequal {0, 1}^* such that L intersection L^- notequalto theta then L is undecidable. T F If L is a context-free language, then L^* is also context-free. T F Given a deterministic turing machine M that takes o(2^n) steps to accept a string of length n, then there always exists a nondeterministic Turing machine N that takes O(n^k) time to accept the same language. T F Any language L subsetorequalto {0}^* is decidable. T F All NP languages are not necessarily undecidable. T F Given a language L subsetorequalto {0, 1}^*, if it is decidable, then it is in NP T F If L is decidable, then L^* is decidable T F All regular languages are in P T F If L is NP and L^- is in NP, then L is in P. T F Union of infinite number of decidable languages is also decidable. T F
