in thread Generate a truth table from input string

the problem that i am facing is, NOT is represented by both ! and ', variables could be !(A)+!(B)+!(C) or A'+B'+C', both mean the same. how do i do it?

    s/(\w+)'/!\1/g

    Rule One: Do not act incautiously when confronting a little bald wrinkly smiling man.
      or as use warnings; would say...
      \1 better written as $1

      and use diagnostics; would elaborate...

      (W syntax) Outside of patterns, backreferences live on as variable +s. The use of backslashes is grandfathered on the right-hand side of +a substitution, but stylistically it's better to use the variable fo +rm because other Perl programmers will expect it, and it works better + if there are more than 9 backreferences.
      Is (a+b)' disallowed?
