Write a Regular Expression (RE) for: The set of strings over alphabet {0, 1} with 011 as a substring Please Answer With Detailed Explanation!
Build a DFA that accepts the set of string over {a,b} in which the number of a’s is divisible by three.
Draw a DFA over the alphabet {a,b,c}that only accepts strings with no c's and an even number of a's, or an odd number of c's and an odd number of b's. For example, it should accept aa, aba, abbabaa, cbacabcb, cbcca, and abc but not aca, bacc, or aaa.
Write Regular expression for the set of strings over {0, 1} that have atleast one 1.
Given two strings A and B, find the minimum number of times A has to be repeated such that B is a substring of it. If no such solution, return -1.For example, with A = "abcd" and B = "cdabcdab".Return 3, because by repeating A three times (“abcdabcdabcd”), B is a substring of it; and B is not a substring of A repeated two times ("abcdabcd").Note:The length of A and B will be between 1 and 10000.Reference: https://leetcode.com/problems/repeated-string-match/description/"""def repeat_string(A, B): count = 1 tmp = A max_count = (len(B) / len(A)) + 1 while not(B in tmp): tmp = tmp + A if (count > max_count): count = -1 break.
With simply the at, length, and substr string methods and the + (concatenate) operator, construct a function that accepts a string s, a start position p, and a length l and returns a subset of s without the characters starting at position p. Strings begin at 0. (“abcdefghijk”, 2, 4) yields “abghijk”.
For the definition of x ∈ EXPR , na(x) denotes the number of a’s in the string, and we will use nop(x) to stand for the number of operators in x (the number of occurrences of + or ∗). Show that for every x ∈ EXPR, na(x)= 1 + nop(x).
Write programs with these input and output Given positive integers m and n, find the number of ontofunctions from a set with m elements to a set with n elements.
List all strings in L whose length is less than 5, where L is defined by the regular expression (a + b)* ba (a + ab)*
Draw 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.l
Write a Program that, given two strings like example and ampleex, can identify whether one of them is a cyclic rotation of the other.
In C language, implement the following two functions that allow breaking a string into non-empty tokens using a given delimiter. For example, For a string "abc-EFG-hi", and a delimiter '-': the list of tokens is ["abc", "EFG", "hi"] For a string "abc-EFG---hi-", and a delimiter '-': the list of tokens is ["abc", "EFG", "hi"] For a string "abc", and a delimiter ' ': the list of tokens is ["abc"] For a string "++abc++", and a delimiter '+': the list of tokens is ["abc"] That is, we break the string using the given delimiter, and the tokens are only the non-empty substrings. 1. The function count_tokens gets a string str, and a char delim, and returns the number of tokens in the string separated by delim. int count_tokens(const char* str, char delim); For example count_tokens("abc-EFG--", '-') needs to return 2. count_tokens("++a+b+c", '+') needs to return 3. count_tokens("***", '*') needs to return 0. 2. The function get_tokens gets a string str, and a char delim, and returns the…
