This project contains a set of problems to help you get your hands dirty with Clojure. I hope we can add more problems and treat this as an ongoing project.
The project is set up so that you can solve problems one by one. All the problem skeletons are set up here, which is the place you can put your solutions.
This project runs within Docker Compose, no need to set up additional dependencies!
To verify your answer, you can run:
$ docker-compose up test
We also implemented solution manual, to run katas with their solutions;
$ docker-compose up answer
Say arranged-prob is not implemented under /src/clojure_katas/sine_angle.clj:
$ docker-compose up test
Performing task 'run' with profile(s): 'test'
Current kata to tackle: clojure-katas.sine-angle/sine
false
After arranged-prob is implemented, it moves to the next problem:
Performing task 'run' with profile(s): 'test'
Testing clojure-katas.sine-angle-test
Ran 1 tests containing 2 assertions.
0 failures, 0 errors.
Current kata to tackle: clojure-katas.arranged-prob/prob
false
Create /src-answers/clojure-katas/arranged_prob.clj for solution.
(defn prob
"p: total population,
m: total number of sub-category,
n: number of consecutive draws"
[p, m, n]
(if (>= 0 n) 1
(* (double (/ m p)) (prob (- p 1) (- m 1) (- n 1)))))Create /src/clojure-katas/arranged_prob.clj for problem challenge.
When using core/defproblem, you are required to put comments to
describe the problem.
(ns clojure-katas.arranged-prob
(:require [clojure-katas.core :as core]))
(core/defproblem prob
"required documentation goes here"
[p, m, n])Creates test under /test/clojure-katas/arranged_prob_test.clj
(deftest arranged-prob-test
(testing "conditional probability"
(is (= (float 0.12311558) (float (prob 200 100 3))))))Add clojure-katas.arranged-prob-test inside the problemsets defined in test_runner
(def problems
'[clojure-katas.sine-angle-test
clojure-katas.arranged-prob-test))Run through solution to make sure it works:
$ docker-compose up answer
We want to keep this project ongoing, if you are interested in helping out, feel free to:
- Open an issue (I will try to be as responsive as possible! :-)).
- Submit a Pull Request (bugfix, or submit a new problem!)
