- 2$\begingroup$ What searching have you done? There are lots of worked examples here (see the reductions tag), and in standard textbooks. If you want help understanding how to do reductions, I suggest reading standard references -- there would be little point in repeating that material. As for your specific exercise, I don't know whether anyone will be interested in doing the exercise for you. You might find this page helpful in improving your question. $\endgroup$D.W.– D.W. ♦2017-06-15 00:24:30 +00:00Commented Jun 15, 2017 at 0:24

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. complexity-theory), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
