For this week's lab we will be creating two separate methods to detect if a user entered string is a palindrome. The first method should ONLY use the string class and/or character class and should compare one character at a time working from the outside in. The second method should use the StringBuilder class and can use any method of that class. Note: Special characters, character case, and spaces should be ignored. Example palindromes follow:a. racecarb. RaceCarc. !Race Card. Ra!ceCa
