• In python initial solution should have 4-space indentation and no final ;.

  • woops... x) (not native either... I guess it's already unraveled... XD )

  • it means look for a pattern or a loop you can use to test the letters. Do not go through every single letter and test it individually.

  • it means "don't hard code everything" (I guess...)

  • English is not my native language. Please, tell me what the phrase "solve this kata without grindin letters" in the "Instructions" mean?
    Am I missing something?

  • add a pic,sloved!

  • There are no random tests in JS version.

  • Provided link is broken so there's no way to decipher braille anymore.

  • Need random test in C++

    Palindromization - Java 1.8.0_91(Java 8)
    I have problem with the exercise. When I run the sample test without modifying the code I get following error message.
    /workspace/java/src/KataTests.java:28: error: class, interface, or enum expected
    1 error

    I noticed that there is addition closing curly brace (}) with no opening brace.

    Default code

    public class Kata {
    public static String palindromization(String elements, int n) {
    return elements;

    Sample Test

    import org.junit.Test;
    import static org.junit.Assert.assertEquals;
    import org.junit.runners.JUnit4;
    public class KataTests {
    public void Error_Cases() {

        assertEquals(Kata.palindromization("", 2), "Error!");
        assertEquals(Kata.palindromization("123", 1), "Error!");
    public void Examples() {
        assertEquals(Kata.palindromization("123", 2), "11");
        assertEquals(Kata.palindromization("123", 3), "121");
        assertEquals(Kata.palindromization("123", 4), "1221");
        assertEquals(Kata.palindromization("123", 5), "12321");
        assertEquals(Kata.palindromization("123", 6), "123321");
        assertEquals(Kata.palindromization("123", 7), "1231321");
        assertEquals(Kata.palindromization("123", 8), "12311321");
        assertEquals(Kata.palindromization("123", 9), "123121321");
        assertEquals(Kata.palindromization("123", 10), "1231221321");

    } // No opening curly brace

  • Thanks! I thought it was my fault

  • In C++ the sample test returned an error with 0 test passed, while the full test were ok

  • Switched their places
