I need some help with these questions for the topic of formal languages Here is all the info: Problem Specification
For each language L to L described below, you need to do the following:
Create a regular expression that defines the language. You will receive up to marks for each
regular expression, depending on how accurately it defines the language. You must use the
definition of regular expressions given in definition using a different definition will lead
to loss of marks. the given definition is: Definition Regular expressionlambda is a regular expression Each symbol in A is a regular expression If r is a regular expression then r is a regular expression and means zero or more repetitions of r If r and r are regular expressions then r r is a regular expression and means r or r If r and r are regular expressions then rr is a regular expression and means r concatenated with r Nothing else is a regular expression
Construct a finite state automaton FSA that accepts the language, then pick a string that is in the
language and show your FSA accepts it and pick a string that is not in the language and show
your FSA rejects it You will receive up to marks for each FSA and tests, depending on their
correctness.
Note that a total of marks are available for this assessment.
The alphabet A a b will be used throughout this coursework. The languages are:
L which has exactly one b but any number of as
L which contains exactly two as or exactly two bs although not necessarily adjacent.
L which has all the bs appearing before any of the as or all the as appearing before any of the bs
L where there can be any number of bs but the number of as must be even, although the as do
not have to be adjacent.
L which has an odd number of bs and an even number of as
