Using JAVASCRIPT, print the count of all the vowels present in the string "Data Structures and Algorithms". The strings contain both uppercase and lowercase vowels.

Find the substring using a string object.

How do you find the non-matching characters in a string through Code.

Given a string str, find the length of the longest substring without repeating characters.  (a).For “ABDEFGABEF”, the longest substring are “BDEFGA” and “DEFGAB”, with length 6. (b).For “BBBB” the longest substring is “B”, with length 1.For “GEEKSFORGEEKS”, (c).there are two longest substrings shown in the below diagrams, with length 7 write code in python

Construct dfas that accept the followings: a. Set of all strings on {0,1} that do not contain two consecutive 0s b. Set of all stings on {0,1} that end with two 0s

Design and implement an application that reads a string from the user and then determines and prints how many of each lowercase vowel (a, e, i, o, and u) appear in the entire string. Have a separate counter for each vowel. Also count and print the number of nonvowel characters.

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

Create a single regular expression that matches a string of digits and contains exactly two fives. Examples of acceptable strings include: "15445 " , " 55 " , " 05563 " . However, the string is to be rejected if it contains anything other than digits.
