Question

Please solve problem 11 and all of its parts. Write down the DFA where it's easy to understand

11. Consider the set of strings on (0, 1) defined by the requirements below. For
each, construct an accepting dfa.
(a) Every 00 is followed immediately by a 1. For example, the strings
101, 0010, 0010011001 are in the language, but 0001 and 00100
are not.
(b) All strings that contain the substring 000, but not 0000.
(c) The leftmost symbol differs from the rightmost one.
(d) Every substring of four symbols has, at most, two 0's. For ex-
ample, 001110 and 011001 are in the language, but 10010 is not
because one of its substrings, 0010, contains three zeros.
(e) All strings of length five or more in which the third symbol from
the right end is different from the leftmost symbol.
Chapter 2 Finite Automata
(f) All strings in which the leftmost two symbols and the rightmost
two symbols are identical.
(g) All strings of length four or greater in which the leftmost two
symbols are the same, but different from the rightmost symbol.
if and only if the value of the

Given Data:

Set of the strings on ${0, 1}$ defined by, following

(a) Every 00 is followed immediately by a 1. For example, the strings $101, 0010, 0010011001$ are in the language, but $0001$ and $00100$ are not.

(b) All strings that contain the substring $000$ , but not $0000$ .
