Implement New Concept Exercise: Bitwise Operators

[andrerfcsantos]

Getting Started

If you have not yet contributed to concept exercises before, this task requires some upfront reading to acquire the necessary background knowledge.

Here you can read about what Concept Exercises are and how they are structured:

• What are Concept Exercises?
• Concept Exercises
• Concepts

Also, be aware of these general guidelines:

• Exercism Markdown Specification
• Exercism Formatting and Style Guide

Goal

The goal here is to create a new concept exercise that teaches about bitwise operators. That includes writing a concept and creating a new exercise.

Concepts

The following concept needs to be created:

• bitwise-operators

You can use the introduction.md file of the concept also as introduction.md file of the exercise. No need to create different content at this point. Additionally, if you want to save some time it is ok to not have an extensive about.md at this point. It can also be mainly the instructions.md content, maybe with some additions you would like to make.

Learning Objectives

The student should learn about the following topics and then practice them in the concept exercise:

• understand what bitwise operators are
• undertstand the operators &, ^, |
• understand bit shift operations << and >>

Out-of-scope

• package math/bits

Prerequisites

• numbers
• arithmetic-operators

These prerequisites should be listed in the config.json entry for the exercise. The prerequisites above are a baseline of the prerequisites that might be needed for the exercise. When implementing the exercise, feel free to add more prerequisites if the exercise needs them.

Story Idea

These are some links to exercises/concepts from other tracks that you might use as inspiration and/or fork them and convert them to Go:

• C# "Bit Manipulation" Concept

• C# "Attack of The Trolls" Exercise

• Elixir "Bit Manipulation" Concept

• Elixir "Secrets" Exercise

If you decide to fork one of the exercises, feel free to add or change some tasks as you see fit.

Resources

Some links that might be helpful as a starting point and/or for the links section of the concept:

• https://yourbasic.org/golang/bitwise-operator-cheat-sheet/
• https://medium.com/learning-the-go-programming-language/bit-hacking-with-go-e0acee258827

How to proceed

1. First accept this issue by saying "I'd like to work on this" (no need to wait for a response, just go ahead).
2. Use this issue to discuss any questions you have, what should be included in the content and whatnot, and to collect more reference material.
3. Create a PR and set "exercism/go" as reviewers. Additionally, you can write in #maintaining-go on Slack that your PR is ready for review. Once you incorporated any critical feedback that the reviewer might give you and the PR is approved, it will be merged by a maintainer.

Hi can i contribute in this issue @andrerfcsantos

[andrerfcsantos]

@Krish-bhardwaj Sure! But before assigning this to you, I want to remind you that it is a significant task and might not be ideal as a first contribution to exercism. But if you feel you are up to the task, don't let me discourage you! Just let me know that you acknowledge that this might require a bit of work and reading some docs beforehand.
