Bright Network Technology Internship 2021 – Google Coding Challenge

This repo contains a solution to the programming challenge set by Google during the 2021 Bright Network Technology Internship work sample. Further details relating to its nature are covered extensively in this document.

The certificate of completion attained can be found here.

Installation & Configuration

Java 11, JUnit 5.4 and Maven 3.8 are required. If you need to install Java for Windows, follow these instructions. Click here for Mac installation instructions and here for Linux.

To install Maven on any of the platforms mentioned above, click this link.

Execution

Any IDE or text editor can be used. However, different editors have different ways of dealing with Java code, so it is recommended to execute the program via your terminal or IntelliJ IDEA.

NOTE: Editing the contents of /resources/videos.txt will cause the unit tests to break.

Via the terminal

Firstly, navigate into java/ then build via Maven by running:

$  mvn compile

Then execute:

$  mvn exec:java

To run all of the unit tests associated with each task, compile the program using:

$  mvn compile

Then:

$  mvn test

To test a specific part of the challenge after compiling, run:

$  mvn test -Dtest=Part1Test
$  mvn test -Dtest=Part2Test
$  mvn test -Dtest=Part3Test
$  mvn test -Dtest=Part4Test

Via IntelliJ IDEA

Follow the official instructions from JetBrains (found here) to open this repository as a Maven project in IntelliJ, which should automatically recognise the java/ directory as such due to the presence of a pom.xml file.

Ensure that the project SDK is set to Java 11 by following these instructions. Any vendor can be used for JDK 11 if it isn't already installed.

To run the entire program, locate and open the Run.java file from the project menu, then click on the green play-shaped symbol positioned in the sidebar.

To run a unit test associated with a part of the challenge, locate /test/ within the project menu, open the specific file, then click on the green double-arrow symbol besides the class name.

Right-clicking the root directory and selecting the "Run 'All Tests'" option from the drop-down menu will do as stated.

Please note that your current version of IntelliJ will most likely not be the same as that shown in the following screen recording summarising the steps above, yet they remain identical.
