# About A list of simple programming challenges that are not only good for beginners, but fun for intermediate/experienced coders. Anyone is welcome to code their own solutions and submit them here! Anyone can: - Take any approach and use any language you wish to solve the challenges. - Solve challenges that have already been solved by somebody else - Submit ideas for new challenges or changes to the list As mentioned above, each challenge can be solved multiple times by multiple people, as the goal of this list is not to solve every single challenge listed, but rather to have the people solving them learn something new and get better at coding. So if there's a challenge which you want to take a shot at, but someone else has already coded a solution for it, then you don't need to worry about it. This repository is also a great way to make your first __pull requests__. To see how to contribute a solution to a programming challenge, see our steps [here](https://github.com/Zsargul/Awesome-Programming-Challenges/blob/master/#How-to-contribute). ### Tips: - If a problem is too easy, choose a language you are unfamiliar with to spice things up! - If you get stuck or overwhelmed, don't become discouraged. Simplify your problem! Use pen and paper, help yourself understand and/or visualise your problem. - Remember that [Stackoverflow](https://github.com/Zsargul/Awesome-Programming-Challenges/blob/master/https://stackoverflow.com/) and Google are your best troubleshooting companions. If you are facing a programming-related issue now, chances are, someone in the past also has! - Don't be afraid to write terrible code. If anything, *this* is the repository to do it! ## CHALLENGES: Due to the fact that the difficulty of each task is VERY subjective, the challenges are not categorized by difficulty. | Challenge | Folder name | Description | |-------------------------------------|--------------------------|-----------------------------------------------------------------------------------------------------------------------------| | Towers of Hanoi | towers_of_hanoi | Simple towers of Hanoi puzzle using 3 rods and N disks. | | Random sentence generator | sentence_generator | Simple random sentence generator.

The folder names for each challenge can be found in the [list above](https://github.com/Zsargul/Awesome-Programming-Challenges/blob/master/#CHALLENGES). __5.__ In that folder, create another folder named after your Github username. That folder will contain your file(s) for the solution you have created. In brief, your submission should look something like this in the file directory: __Example:__ ``` temperature_converter/your_username/your_solution.py ``` for a single file, or: ``` temperature_converter/ └── your_username/ ├── solution_file1.py └── solution_file2.py ``` for a multi-file solution. __6.__ Add, commit and push your solution to your fork using these commands: ``` git add . git commit -m "description of changed files" git push -u origin your_new_branch ``` __7.__ After successfully pushing, you can finally submit your solution by opening up a pull request through your fork on your web browser. If you do not know how to do this, see [the following](https://github.com/Zsargul/Awesome-Programming-Challenges/blob/master/https://opensource.com/article/19/7/create-pull-request-github). ## Submitting new challenges or changes to the current list You are also free to suggest new challenges to the list or changes to the current ones. You can do so with a regular pull-request or by opening an issue.
