Use regular expression to implement a function which accepts a passed string and check if it is a valid email address. A program accepts user's input and calls the email validation function. If the email is valid, print out the email, username and host. (Rule: word characters (a-zA-Z0-9_ or "w"), dot, and hyphen are considered as valid characters in an email address, besides of one & only one (Sample output as shown in the following figure is for demonstration purposes only.) In [24]: runfile('C:/tmp/units/2020/SIT384-2020-1/portfolio/week2/ Task2.3P.py', wdir='C:/tmp/units/2020/SIT384-2020-1/portfolio/week2') Please input your email address:teste Not a valid email. Please input your email address:shang.gao@test2.server.com email: shang-gao@test2.server.com, username: shang-gao, host: test2.server.com Submission: Submit the following files to OnTrack: 1. Your program source code (e.g. task2-3.py) 2. A screen shot of your program running Check the following things before submitting: 1. Add proper comments to your code

A palindrome is a string that reads the same both forward and backward. For example, the string "madam" or “level” are a palindrome. Write a program in C++ that uses a function to check whether a string is a palindrome. Your program must contain a value-returning function that returns true if the string is a palindrome and false otherwise. note: use DSA concepts
-Python3-
Define a function generate_new_string that takes an integer times and a string string and - returns a new string such that is a concatenation of times copies of string. For example: Test Result print (generate_new_string(2, 'aa')) aaaa

Python program question(details in the picture)
// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }
Write a function that parses a decimal number into a binary number as a string. Use the function header:def decimalToBinary(value): Write a test program that prompts the user to enter a decimal integer value and displays the corresponding binary value.
In Python: Define a function in which a string is passed as a parameter and the function returns true if the length of the string is a multiple of 3. Otherwise, the function returns false.

use c code to Develop a function that gets two same length strings as parameters and reports the number of characters that they have different. For example, if the two strings are Str1: “Hello world! Happy Friday”Str2: “Hello Johny! happy friday” The function should return: Your strings are different in 7 places However, if the strings are exactly equal, it should just say Your strings are the same If the strings are not of the same length, the code should just say: The two strings are not of the same length! Hint: 1.compare the two strings character by character and report the differences 2.answer must have and show the output
