Given the language, L = {ab, aa, baa}, which of the following strings are in L*?
1. abaabaaabaa

3. baaaaabaaaab
4. baaaaabaa
Consider the set of strings on {0,1} in which, every substring of 3 symbols has at most two zeros. For example, 001110 and 011001 are in the language, but 100010 is not. All strings of length less than 3 are also in the language. A partially completed DFA that accepts this language is shown below
The missing arcs in the DFA are
