blog-catalan

A trial Clojure project for a blog post about the Catalan Numbers.

Usage

core namespace

The namespace contains three basic functions:

• factorial counts a factorial.
• binomial counts a binomial coefficient.
• catalan counts a Catalan number.

All these funcitons build on top of each other - catalan uses binomial which uses factorial.

Additionally, there is a function catalans which returns a lazy sequence of the Catalan numbers.

recur namespace

The namespace contains a catalan function which counts a Catalan number via recursion.

Midje tests

You can run all Midje tests by lein midje.

REPL

You can load the functions into the REPL with:

(require '[blog-catalan.core :as c]
         '[blog-catalan.recur :as r])

(c/catalan 5)
(r/catalan 5)
