No. For example, take the following grammar: E -> TE’ | T E’ -> +TE’ | -TE’ | T T -> FT’ | F T’ -> *FT’ | /FT’ | F F -> cte | (E) It is the well known grammar for arithmetic expressions, written in LL(1) form. It is also a well known … Read more
If you’re just asking for a way to parse the variable bits from this kind of text, it’s quite easy: See here: http://tinyurl.com/qjdaj9w var exp = new Regex(@”angle\(Vector\((.*?),(.*?)\),Vector\((.*?),(.*?)\),(.*?),(.*?)\)”); var match = exp.Match(“angle(Vector(JointA,jointB),Vector(JointA,jointB),minValue,maxValue)”); var jointA1 = match.Groups[0]; var jointB1 = match.Groups[1]; var jointA2 = match.Groups[2]; var jointB2 = match.Groups[3]; var max = match.Groups[4]; var min = … Read more
How is it possible that the language a^n b^2n is regular if and only if it was finite such that 100 => n <= 0? [closed] solved How is it possible that the language a^n b^2n is regular if and only if it was finite such that 100 => n
re.findall(r”‘https://.*?'”, part_of_html) re.findall(pattern, string, flags=0) Return all non-overlapping matches of pattern in string, as a list of strings. The string is scanned left-to-right, and matches are returned in the order found. If one or more groups are present in the pattern, return a list of groups; this will be a list of tuples if the … Read more
