# collatz

The [Collatz conjecture][wiki] in Clojure as a lazy sequence. Also includes a neat visualisation inspired by [this awesome video][numberphile], you can run the visualisation with `lein run`.

Nothing will render until you hit the `Enter` key, and even then it may take a little while, it's fairly CPU intensive.

> Visualisation is still completely wrong right now, it still looks kind of neat, but it's not the final product.

You'll find the actual Collatz sequence function in the `collatz.core` namespace.

```clojure

(ns cool.thing

  (:require [collatz.core :as c]))

(first (c/collatz 1000)) ;; Returns 1000, the seq starts where you specify and counts down.

(last (c/collatz 1000)) ;; Returns 1, as it always will be, I assume?

```

If the last value is ever not 1, notify your closest mathematician and run.
