Question

Let = {0, 1}. Which language is expressed by the regular expression *011*

{w | w contains 011 as a substring after the first symbol}

{w | w contains 011 as a substring}

{w | w has length at least 4 and contains 011 as a substring}

{w | w contains 011 as a substring after at least one symbol}

{w | w contains 011 as a substring after the first symbol}

{w | w contains 011 as a substring}

{w | w has length at least 4 and contains 011 as a substring}

{w | w contains 011 as a substring after at least one symbol}

Here given that = {0, 1}

The expression is *011*

So it represents the two symbols. Those are preceded by the substring 011

So here there should be atleast one symbol before the substring. So in the option given that substring after at least one symbol

So the correct answer is option (d) w | w contains 011 as a substring after at least one symbol.
