# Reference for the Tortoise and Hare algorithm by Floyd?

Can someone please point me to a book or paper that describes the Tortoise and Hare algorithm by Floyd?

I know there are ample websites out there, but for reference purposes, I need a book or paper to point to.

• I don't want wikipedia. I want a book, or paper. Because you can put as reference the wikipedia. – Mr. Zacarias Satrustegui Jul 24 '18 at 11:45
• I'm not suggesting you reference Wikipedia. I'm suggesting you go through the references mentioned on Wikipedia and if they have what you want, you put these books and papers as your references. – SEJPM Jul 24 '18 at 11:46
