Write a Perl program which simulates the operation of finite automata.

The finite automata are represented using transition tables. They are restricted to a maximum of 10 states labelled 0-9, with start state 0. Their alphabets are restricted to a maximum of 26 lower case symbols a-z. The alphabet and transition tables of the finite automaton are specified in blank-seperated fields. The first line specifies the alphabet of the finite automaton, representing end-of-strings as #. The next line represent the rows of the transition table in order. The error condition is represented as ! and the accept condition by *. The line specifying the last row of the transition table is followed by a blank line, followed by zero or more lines representing the input strings, one string per line. The program must read the alphabet, the transition table and the input strings and for each string it must print, on one line, “Accept” or “reject”, followed by the input string. Input strings containing illegal symbols not in the machine’s alphabet must be rejected. The report on the final string must be followed by one blank line.

The following lines for example represent a 3-state finite automaton which accepts strings over the alphabet {a,b} which contain double-b, followed by strings to be analysed: 

a   b   #
0   1  !
0   2  !
1   2  *
<blank line>
aababa
babbaab
abaaabbaa
bbx
<blank line>

Given this input your program must output the following results: 
Reject aababa
Accept babbaab
Accept abaaabbaa
Reject bbx
<blank line>

The representations of zero or more finite automata and their strings are given in a file. The program must write output to a file.
