WebL = { w : w contains the substring bbb } It's also easy to see that a regular expression for L is (a∪b) * bbb(a∪b) *, since we only need to find the substring bbb somewhere in the string, not necessarily finding the first occurrence, which is what the DFA does. DFAs for substring acceptance The previous example can be generalized. WebSolutions for Chapter 1 Problem 6E: Give state diagrams of DFAs recognizing the following languages. In all parts, the alphabet is {0,1}. a. {w w begins with a 1 and ends with a 0} b. {w w contains at least three 1s} c. {w w contains the substring 0101 (i.e., w = x0101y for some x and y)} d. {w w has length at least 3 and its third symbol is a 0} e. {w w starts …
