Palindrome check

A palindrome reads the same forwards and backwards. Return true if s does, ignoring case and spaces, so Race car counts. Clean the string first (toLowerCase, remove spaces), then compare characters moving inward from both ends.

Complete isPalindrome(String s) so it returns true when s reads the same forwards and backwards, ignoring case and spaces.

public class Pal {
    public static boolean isPalindrome(String s) {
        return false;   // change this
    }
}
