Question: Let L1 be a formal language using the binary digits 0 and 1 as its character set, such that a string is in L1 if

Let L1 be a formal language using the binary digits 0 and 1 as its character set, such that a string is in L1 if and only if it has 2 or more adjacent 0s somewhere in it.

A. Draw a deterministic finite state automaton (FSA) that recognizes L1. N.B. it may be easier to draw a NFA first and convert it.

B. Write a regular expression whose language is L1.
