Question.Use Python Code Correctly to solve this problem.A phrase is a palindrome if, after converting all uppercase letters into lowercase letters andremoving all non-alphanumeric characters, it reads the same forward and backward. Alphanumericcharacters include letters and numbers.Given a string s, return true if it is a palindrome, or false otherwise.Example 1:Input: s= "A man, a plan, a canal: Panama "Output: true Explanation: "amanaplanacanalpanama"is a palindrome.Example 2:Input: s = "race a car"Output: falseExplanation: "raceacar" is not a palindrome.Example 3:Input: s = " "Output: trueExplanation: s is an empty string after removing non-alphanumeric characters.Since an empty string reads the same forward and backward, it is a palindrome.Constraints:1 <= s.length <= 2 * 105s consists only of printable ASCII characters.11 11
