Anagram Coding Challenge

Definitions​:

Anagram: a word, phrase, or name formed by rearranging the letters of another, such as
cinema,​ formed from ​iceman​.

Problem​:

Please complete any or all of these problems in a public GitHub repository, and provide a link to the repository. Any documentation on running the solution will be appreciated.

1. Create a function which takes two ​String​ arguments, and returns a ​Boolean corresponding to whether or not the two ​String​ arguments are ​anagrams​ of each other.

2. Provide some unit tests for the function implemented in step 1.

3. Create a HTTP server which implements the following:

   a) Endpoint ​/anagrams/{string1}/{string2}

   • Returns a ​400​ - ​Bad Request​ if either s​tring1​ or ​string2​ are not valid

   • Returns a ​200 - OK​ with the following ​JSON​ payload: { ​areAnagrams​: true|false } where ​areAnagrams​ is true or false, depending on whether ​string1​ and ​string2 are ​anagrams​ of each other.

     b) Endpoint ​/anagrams/{string1}

   • Returns a ​400 - Bad Request​ if s​ tring1​ is not valid

   • Returns a ​200 - OK​ with the following ​JSON p​ayload: { anagrams: [ … ] } where anagrams is an array of all possible anagrams of ​string1

4. Provide some unit/integration tests for the server implemented in step 3.

5. Containerize your project in a Docker container and include the Dockerfile and
   docker-compose files with you project

Solution:

• Java-Spark; a tiny framework to make for a smaller container size;

• Multi-stage Docker Build to reduce final container size

• Junit 5 unit tests

• Integration tests using Postman Collection (with JavaScript’s Chai framework) and newman

• For the problem 3b, I’ve decided to used one of the english dictionary available in all distribution on linux. For the simplicity of the solution, I have provided the one from the Mac OS X distribution.

Welcome to web2 (Webster’s Second International) all 234,936 words worth.
The 1934 copyright has lapsed, according to the supplier.

Only same length anagrams is returned for simplicity.
## Build and run the solution with docker:
```shell script
docker-compose up --build anagramServer

Test:

Integration tests:

```shell script
docker run —network host -t postman/newman run “https://www.getpostman.com/collections/7f56d87ab98e182e9f9a“

### Manual:
```shell script
curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET http://localhost/anagrams/cinema/iceman
