Question: 2 (6 points) Describe the error in the following proof that 0'1' is not a regular language. (An error must exist because 0*1 is regular.)
2 (6 points) Describe the error in the following "proof" that 0'1' is not a regular language. (An error must exist because 0*1 is regular.) The proof is by contradiction. Assume that 0*1' is regular. Let p be the pumping length for 01 given by the pumping lemma. Choose s to be the string 0P1P. You know that s is a member of 0*1', but Example 1.73 shows that s cannot be pumped. Thus you have a contradiction. So, 0'1' is not regular
