Write a method that checks whether the input string or a sentence (a string with spaces) is a palindrome or not. The method should be case insensitive and should ignore spaces. Write a test program that prompts the user to input a string and invokes this method. Some example runs are: Enter the input string: madam Input string madam is a palindrome Enter the input string: banana Input string banana is NOT a palindrome Enter the input string: Race Car Input string Race Car is a palindrome Enter the input string: Too HOT to hoot Input string Too HOT to hoot is a palindrome
