Simple Unchanging Rules

The code challenge is and will always be judged using the following criteria:

• Using the GitHub Pull Request Time Stamp and correct code quality & structure, we unfortunately won't be able to consider any code challenge that goes over the timeline stated above.
• Code quality and structure will be evaluated by the team
• Do not share any code that you cannot opensource on the Git Repository as its open source and Africa's Talking will not be liable for any breach of intellectual property (if any) once shared on the platform.
• Complete both challenges below

Terms and Conditions

• Code Challenges are time bound - the time restriction is specified on the challenge
• Additional rules MAY be provided on the code challenge and will vary for each challenge

Code Challenge Bounty:

Task 1

Those structures though...

Play around with these structures, make sure the logic and the approach are tight.

With the assumption that you are using an object oriented programming language, write a program that given hundreds of documents, can find all documents with words containing the letter "a" in them.

Tips

Map then reduce

Comment your code to show your thought process

You can submit this as a file in your pull request named "task 1"

Task 2

Send and validate

Play around with some of our products.

Create a simple USSD + SMS app that does user registration.

User journey: person dials the USSD Code and gets prompted for a username and email address. After which they get an SMS response telling them they've registered successfully

Pull all changes, make sure your repository is up to date

$ cd June_2019_Challenge
$ git pull origin master

Create a new branch as follows-> git checkout -b [your name], e.g.

$ git checkout -b roina_ochieng master

See all branches created

$ git branch
* roina_ochieng
  master

Push the new branch to github

$ git push origin -u roina_ochieng

3.Make changes to the fork following the Code Challenge provided.

4.Commit the changes to your fork.

5.Make a pull request to the January_2019_UiUx_Challenge Repo.
