Exercises that I am doing when learning clojure.

clojure-learn

TODO Description

List of Modules

• bigint : For infinite precision integer arithmetic
• diagnonal :
• triplet :
• clock : convert time from 12-hour format to 24-hour format
• position : find the index of the given number in an array

Using the Gorilla Repl

• Add :plugins [[lein-gorilla "0.4.0"]] to project.clj
• Run lein gorilla to launch the repl

Adding a new module

To add a new module called XXX

Code

• Add a new file src/XXX.clj
• At the top of the file, add the name space for this module

(ns clojure-learn.XXX (:gen-class))

Test Cases

• Add a new file test/XXX_test.clj
• At the top of the file add the namespace of the test and all the dependencies

(ns clojure-learn.XXX-test
  (:require [clojure.test :refer :all]
            [clojure-learn.bigint :refer :all]))

To run all tests in project

lein test

To run all tests for XXX

lein test clojure-learn.XXX-test

To run only a specific test

lein test :only clojure-learn.bigint-test/name_of_the_test

HackerRank Notes

The HackerRank Environment for Clojure imposes a 8second time limit for execution, and a maximum memory consumption of 512MB

TODO

General

• Support for debug printing

bigint

• SUBTRACT works only for +ve numbers and where v1 > v2
• no support for MULT, DIV, or MOD
