The 2005 CyberArmy Pig Latin Contest! ;) |
||
 CinC snarkles I'm in the process of doing this one myself but it's looking pretty sketchy really fast. ;) So I figured I'd post this here as a little "challenge" for folks, in case someone can do it faster/cleaner than I can (which is a very distinct possibility ;)). YOUR MISSION, should you choose to accept it, is to make the PigLatinCipher class. (Wtf is Pig Latin?) Here, I'll even give you a template to get you started: package net.cyberarmy.sneak.algorithm;
import net.cyberarmy.sneak.algorithm.template.AlgorithmException;
import net.cyberarmy.sneak.algorithm.template.Cipher;
/**
* An implementation of <code>Cipher</code> that translates input
* to Pig Latin (see: http://en.wikipedia.org/wiki/Pig_latin)
* <br><br>
* <i>foobar</i> becomes <i>oobarfay</i><br>
* <i>onion</i> becomes <i>onionway</i><br>
* <i>strawberry</i> becomes <i>awberrystray</i>
*
* @author yournamehere
* @since 05.04.2005
*/
public class PigLatinCipher extends Cipher {
/**
* Translates given input data to Pig Latin.
*
* @param input The input data to translate.
* @return The translated input data.
*/
public String execute(String input) throws AlgorithmException {
if (input == null) {
throw new AlgorithmException("The input may not be null!",
new IllegalArgumentException());
}
// YOUR CODE HERE
}
/**
* Translates given input data from Pig Latin.
*
* @param input The input data to translate.
* @return The translated input data.
*/
public String reverse(String input) throws AlgorithmException {
if (input == null) {
throw new AlgorithmException("The input may not be null!",
new IllegalArgumentException());
}
// YOUR CODE HERE
}
}
The catch??
All of these unit tests must pass! Mwahahahahahahaaa! package net.cyberarmy.sneak.junit.tests;
import junit.framework.TestCase;
import net.cyberarmy.sneak.algorithm.PigLatinCipher;
/**

public class PigLatinCipherTest extends TestCase {
private PigLatinCipher pigLatin;
public PigLatinCipherTest(String name) {
super(name);
}

pigLatin = new PigLatinCipher();

...and any other random ones that people can think of. ;P
How to get started? If you have troubles with any of the below, check out the Developer's Guide, or post back here with any questions. 1. First of all, use Subversion checkout the source. 2. Save the above two chunks of code as: #1: PigLatinCipher.java in (wherever the source was checked out)/trunk/desktop/src/java/net/cyberarmy/sneak/algorithm/ #2: PigLatinCipherTest.java in (wherever the source was checked out)/trunk/desktop/src/junit.tests/net/cyberarmy/sneak/junit/tests/ 3. Code away until all of the unit tests in PigLatinCipherTest pass! (aka the Ant build runs properly) Regexes will likely be your friend here: see the docs on java.util.regex Post submissions as a reply to this thread. Winners will be based on:
Note too that these should be original code submissions, and that any submissions here may be crufted together to use in the final version for SNEAK (with proper credit given, of course). So make sure you're comfortable with your code being released under the GPL. I'll arbitrarily set a contest end date of May 01, 2005, which gives folks about a month to participate. Avehay Unfay! ;) Replies:
