Implement two methods (using iterative and recursive approaches) to check if a given input string is a palindrome or not. Example 1: Input: [”radar”] Output: [true] Example 2: Input: [”radio”] Output: [false] ˆIterative Approach: public static boolean palindrome_iterative (String str) { } ˆRecursive Approach: public static boolean palindrome_recursive (String str) { }
