Q: Write regular expression for the following languages. All strings in which b is never tripled. It means that no words contain the substring bb. All the strings accepting b as second letter. Regular expression that accept only prime numbers. All the strings that start with aa, end with bb, and have alternating substrings ba in between. Language of all those strings with length greater than 3

Part 3 plase skip it if you dont know the correct answer i need it urgent. Will doewnvote in case of wrong or copied answers from chegg or bartleby! A regular expression (shortened as regex or regexp; also referred to as rational expression) is a sequence of characters that specifies a search pattern. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. using regex create a python program to verify the string having each word start from 'f'? It should return True otherwise false.
remove_substring_from_string(s, substr): This function takes two strings s and substr as input. It creates a new string from the original string s by removing all instances, if any, of the string substr, and then returns the new string. >>> remove_substring_from_string("Python is best language except for C++. except for C++") 'Python is best language.

String Manipulation In this question, you will be implementing the following functions int findChar(char * str, char c); Searches for the character c in the string str and returns the index of the character in the string. If the character does not exist, returns -1 int replaceChar(char * str, char c1, char c2); Searches for the character c1 in the string str and if found, replace it with c2.The function returns the number of replacements it has performed. If the character does not exist, returns 0. int removeChar(char * str1, char * str2, char c); Creates a copy of str1 into str2 except for the character c that should be replaced with ‘*’ For example, if str1=”Hello World” and c=’l’ then the function should make str2=”He**o Wor*d” int isPalindrome(char * str) Checks to see if a string is Palindrome(reversible). If it is, returns 1, otherwise returns 0. A palindrome string reads similarly from left to right and from right to left like madam, level, radar, etc. int reverseString(char…
s = "abab" h 55m Left Substrings in s are { 'a', 'b', 'a', 'b', 'ab', 'ba', 'ab', 'aba', 'bab', 'abab'}. By deleting one "a" and one "b", the string becomes "ab" or "ba" and all of its substrings are distinct. This required 17. String Reduction 2 deletions. Given a string, reduce it in such a way that all of its substrings are distinct. To do so, you may delete any characters at any ALL index. What is the minimum number of deletions needed? Function Description Complete the function getMinDeletions in the editor below. Note: A substring is a contiguous group of 1 or more characters within a string. getMinDeletions has the following parameter(s): Example string s: the given string 8 S = "abab" Returns: int: the minimum number of deletions required Substrings in s are { 'a', 'b', 'a', 'b', 'ab', 'ba', 'ab', 'aba', 'bab', 'abab'}. By deleting one "a" and one "b", the string becomes "ab" or "ba" and all of its substrings are distinct. This required Constraints 2 deletions. 10 1sns 105…
Exercise Objectives Problem Description Write a program that reads a string and mirrors it around the middle character. Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.
Fix the errors and find the lowest marks entered by the user struct std{string name;int reg_no;int marks[5];}s1;getline(cin,s1.name);cin>>s1.reg_no;for(int i =0;i<5;i++)cin>>s1.marks[i]
2) Design NFA that accepts the set of strings over (a, b} such that there should be at least one substring which starts and ends with a b and the number of symbols between these two b's is divisible by 4. Example: abababaaaababab, babbaa (since 0 is divisible by 4), ababababbaa
19. Given: Σ = {0, 1}, write regular expressions for the following languages: Strings that have a length of at most three. Strings that have a length divisible by 3. Strings that have no more than two 0s. Strings that do not end with 11. Strings that consist of only 1s and interpreted as a binary number are even
Specification: Read sentences from the user until * is entered. Show the number of words in each sentence that contain a stretch of non-z characters with exactly 2 vowels. A stretch starts from the start of the word or after a 'z'. A stretch terminates just before another 'z' or at the end of the word. Examples: 1. Matching words: zoo, azozooza, GONZALEZ 2. Non-matching words: ozo, azoooza The sentences contain no punctuation, the words are separated by one or more spaces, and the characters may be upper or lower case. Keep reading sentences until the user enters "*". Sample I/O: Sentence: azoooza azooza zoo azoo Matching words = 3 Sentence: GONZALEZ passes the ball to VAZQUEZ Matching words = 3 Sentence: azozototzeti Matching words = 1 Sentence: * Done
