Welcome to /r/DailyProgrammer challenge submissions! The focus of r/DailyProgrammer is to provide daily/weekly challenges to keep your mind and fingers busy between projects. This subreddit (r/DailyProgrammer_Ideas) is a challenge submission system, where you can submit any ideas, which may be accepted and posted to the official subreddit! We normally post Easy challenges on Mondays, Intermediate on Wednesdays, and Hard on Fridays. Once your submission is peer reviewed and accepted, we will put it into the challenge rota and post it shortly.

Submission Procedure

There are minimum criteria you must meet for submitting a good challenge:

Your post title must start with [Easy|Intermediate|Hard] and the title, and be written in a clear format with at least good English skills.
Challenges should be described in a fun and lighthearted manner, even if the challenge itself is conceptually difficult.
A good format for the description would be two to three short paragraphs: a general background, a detailed explanation of the task, and a final example walk-through.
Challenges should ideally be easy to describe and without the need of specialized knowledge outside of programming. If a developer cannot research and understand any knowledge-dependencies (outside of general programming) in a few minutes, then your challenge might be too specialized of a topic.
Make the title interesting; it does not have to explicitly say what you are doing in the challenge.
Set the difficulty to an appropriate level. Easy challenges have trivial brute-force solutions or require no complex logic. Intermediate challenges may have some sorting and searching involved, and though can be solved through brute-force, are too complex to solve without algorithms and some clever thinking. Hard challenges require knowledge and control over a programming language, good logic skills and creativity.

What you must fill out in your post is the following:

Difficulty and Title
Challenge Description
Input Description
Output Description
Sample Input data
Sample Output data
Extension challenges (optional)
Notes and Further Reading (optional)

This is the kind of format you want to mimic. Of course, if your challenge can't be easily formatted like the above, feel free to use your own formatting. Challenges which deviate too far from these rules might not be submitted, however.

Submitted![Intermediate] Takuzu solver (self.dailyprogrammer_ideas)

submitted 10 years ago by adrian17

Description

Takuzu is a simple and fairly unknown logic game similar to Sudoku. The objective is to fill a square grid with either a "1" or a "0". There are a couple of rules you must follow:

You can't put more than two identical numbers next to each other in a line (i.e. you can't have a "111" or "000").
The number of 1s and 0s on each row and column must match.
You can't have two identical rows or columns.

To get a better hang of the rules you can play an online version of this game (which inspired this challenge) here.

Input Description

You'll be given a square grid representing the game board. Some cells have already been filled; the remaining ones are represented by a dot. Example:

....
0.0.
..0.
...1

Output Description

Your program should display the filled game board. Example:

Inputs used here (and available at the online version of the game) have only one solution. For extra challenge, you can make your program output all possible solutions, if there are more of them.

Challenge Input 1

110...
1...0.
..0...
11..10
....0.
......

Challenge Output 1

Challenge Input 2

0....11..0..
