It accepts 1010, 0101,110110, etc. but does not accept 01, 0110, 1101, 00, etc. Ʃ={0, 1}Built regular expression of the following. 1. A language of any combination of even number of a's and even number of b’s containing abb as a substring. 2. Write an RE for the language L = {0^1m | where m + n is odd}. 3. All string does not contain the substring 'aaa' but has exactly one 'a'
- Write regular expressions for the following languages on {0, 1}. A. all strings ending in 10, B. all strings not ending in 10,Write in C sharp programming We are given a string containing a list of forbidden words and a text containing some of these words. Write a program that replaces the forbidden words with asterisks. Example: Words: "PHP, CLR, Microsoft" The expected result: Microsoft announced its next generation PHP compiler today. It is based on .NET Framework 4.0 and is implemented as a dynamic language in CLR. ********* announced its next generation *** compiler today. It is based on .NET Framework 4.0 anFind two strings belong to the language represented by the following regular ?expressions * ab)*b) إجابتك * a(alb)*a إجابتك * a(a+b)2 إجابتك *baa إجابتك *(ab+b) إجابتك * aa+bb إجابتك صفحة 3 من 6
- For each one of the following languages over alphabet {a, b}, write an equivalent regular expression. (a) All strings made out of zero or more b's: (b) All strings that do not start with bb. (c) All strings that end with aaa or bb (d) All strings that start and end with the same alphabet letter.L={a*b™a" | n,m=1,2,3....} is given. i) Write a CFG for the language L.Recursive Syntax The recursive structure i.e of natural language like English can be expressed in syntax rules written in the format known as BNF (Bachus-Naur Form). While BNF is ordinarily used as a guide for parsing (that is, determining whether and how a given string follows the syntax rules), An example of this can be found in the sample program SimpleRandomSentences. You should write a similar program that implements the following rules:<sentence> ::= <simple_sentence> [ <conjunction> <sentence> ]<simple_sentence> ::= <noun_phrase> <verb_phrase><noun_phrase> ::= <proper_noun> |<determiner> [ <adjective> ]. <common_noun> [ who <verb_phrase> ]<verb_phrase> ::= <intransitive_verb> |<transitive_verb> <noun_phrase> |is <adjective> |believes that <simple_sentence><conjunction> ::= and | or | but | because<proper_noun> ::= Fred | Jane | Richard Nixon | Miss…
