Sequence

Palindrome

Core exercise

Write estPalindrome(String texte) that returns true if the string reads the same in both directions. Characters are compared as they are (case-sensitive, without ignoring spaces). The empty string is a palindrome.

A workshop goes here: you write and run code in it. It requires JavaScript.

Starting code

Exercices.java

public class Exercices {

    public static void main(String[] args) {
        System.out.println(estPalindrome("radar"));
        System.out.println(estPalindrome("java"));
    }

    public static boolean estPalindrome(String texte) {
        // TODO
        return false;
    }
}

The core exercise is validated in the workshop, which requires JavaScript.

Hint 1

Two indices moving towards each other: one at the start, one at the end. Or compare charAt(i) with charAt(length - 1 - i) over the first half.
