Hello,
I am fairly new at this and doing it as a hobby. I am not familliar
with Grammers but this looked like it was mistyped. Please correct me if I
am
wrong.
On Page 95 at the top.
"3. Suppose r and s are regular expressions denoting the languages L(r)
and
L(s). Then,
<Snip>
c) (r)* is a regular expression denoting (L(r))*.
d) (r) is a regular expression denoting L(r). Footnote"
Footnote: This rule says that extra pairs of Paren may be placed aroung
regular expressions if we desire.
Shouldn't the Footnote go after c and not d? I only posted because this
troubled me and I saw others post Errata for the book on here. Thank you.
Josh
