- Write regular expressions of the following languages- The set of strings that start and end with the same symbols 01. Σ = {0,1,2} The set of strings that contain both substrings ‘101’ and ‘000’. Σ = {0,1} The set of strings having 0 at every 3rd position from the beginning. Σ = {0,1}. For example- 000, 010, 0100100, 110110, etc. The set of strings that do not contain substring ‘10’. Σ = {0,1} The set of strings that do not end with ‘01’. Σ = {0,1} Following is an example of different ways one can declare variables in some programming language.Write down the regular expression that can generate such variable declarations.Assume that- All variable names are at most five (previously written as exactly five; both will be considered correct) characters long. Variable names can contain only small letters [a-z], digits [0-9], and two special characters $ (dollar) and _ (underscore). $ sign can only be used at the beginning. No names can start with digits. The variable types…Given the following regular expressions, write, for each of them, a word that belongs to the language that the expression represents and another that does not belong to said languagea.

By "word", we mean an alphabetic string separated from other words by whitespace, any relevant punctuation, line breaks, and so forth. 1. the set of all strings with two consecutive repeated words (e.g., "Humbert Humbert" and "the the" but not "the bug" or "the big bug"); 2. all strings that start at the beginning of the line with an integer and that end at the end of the line with a word; 3. all strings that have both the word grotto and the word raven in them (but not, e.g., words like grottos that merely contain the word grotto); 4. Demonstrate a pattern to check if the email address is valid. 5. Demonstrate a pattern to verify the validity of a phone number, and check if it belongs to the Pakistani Mobile Network. 6. Demonstrate a RE to remove symbols and non-alphanumeric characters from the string paragraph. 7. Demonstrate a RE to remove URLs and HTML tags from the text string.
