-## Contribution Guidelines
-
-### 1. Contribution Specifications
-
-The problem being contributed must either be a simple **file** (**Eg.** [`kruskal-algorithm.cpp`](./algorithms/CPlusPlus/Graphs/kruskal-algorithm.cpp), [`linear-search.java`](./algorithms/Java/searching/linear-search.java)) or a more complex **directory** ([`palindrome/`](./algorithms/Rust/strings/palindrome)). This is a unit `problem`.
-
-The directory tree has the following convention of `algorithms/{language}/{category}/{problem}`, where `{language}` represents the language code of the problem (**Eg.** `CPlusPlus` for C++, `CSharp` for C# etc.), `{category}` is the topic or category of the problem being contributed (**Eg.** `strings`, `sorting`, `linked-lists` etc.), and `{problem}` is a conforming name to the problem (**Eg.** `linear-search.cpp`, `palindrome`, `queue-linked-list.cpp` etc.)
-
-A unit `problem` must conform to the following specifications:
-
-- The name should be in lowercase. (**Eg.** `palindrome/`, `binary-search.cpp` etc.).
-- Each word must be separated by a **dash** or a **hyphen** (`-`).
-
-**If you have a problem that belongs to a new _topic_ or _category_ than one which are present:**
-
-1. Create a new folder and an index for it inside (a readme, `README.md` file).
-2. To each new index file, write the readme with your `problem` in it ([Markdown Documentation](https://guides.github.com/features/mastering-markdown/)).
-3. The folder name can also only contain **lowercase characters** and **dashes** or **hyphens** (`-`) (Eg. `strings` `sorting` etc.)
-
-#### Simple (File) Contributions
-
-The file should conform to the `problem` specification, and the extension (**Eg.** `linear-search.java`, `kruskal-algorithm.cpp`, `count-inversions.js` etc.)
-
-#### Project/Folder-based Contributions
-
-The project and folder-based contributions have a bit more stricter contribution contribution specifications.
-
-The folder should conform to the `problem` specification, along with the following specifications
-
-**Folder Structure**
-
-```bash
-problem-name\
-| - .gitignore
-| - README.md
-| - Makefile # or the specific specification/requirements/configuration file
-| - src\
- | - main.ext
-```
-
-#### `README.md` Specification / Template
-
-````markdown
-#
-
-< description of the problem >
-
-## Prerequisites
-
-- prerequisite library or package
-- [prerequisite library](https://www.example.com/link-to-official-library)
-
-## Instructions
-
-- instructions to run the project
-- < Simple and reproducible commands to execute the project >
- ```bash
- make # or 'cargo run', or 'dotnet run' or 'mvn exec:java' etc.
- ```
-
-## Test Cases & Output < if exists>
-
-< If you can provide test cases, describe it here, else remove this section >
-````
-
-#### `.gitignore` File
-
-```gitignore
-# add all output files and build files to be excluded from git tracking
-main # executable file also must have the project name
-target/ # the build file, for example for rust
-```
-
-#### Build File / Specification File / Configuration File
-
-It can be any of the following ones
-
-- **C/C++**: `Makefile`
-- **Python**: `requirements.txt`
-- **JavaScript**: `package.json` and `package-lock.json`
-- **Rust**: `Cargo.toml` and `Cargo.lock`
-- **Go**: `go.mod`
-
-#### Source Code File
-
-The source code files, should either be in `src/` folder (**Eg.** `src/main.cpp` or `src/main.js`) or the root folder (**Eg.** `palindrome.go` or `App.java`) where `ext` is the file extension for the specific programming language.
-
-Again, the source codes must conform to a valid file structure convention that the programming language enforces.
-
-### 2. Naming Convention
-
-The programming should keep the naming convention rule of each programming language.
-
-### Other topic

-# প্যালিন্ড্রোম
-প্যালিন্ড্রোম হল একটি শব্দ, শব্দগুচ্ছ, সংখ্যা বা শব্দের ক্রম যা সামনের মতো পিছনের দিকে পড়ে। শব্দ বা অক্ষরের মধ্যে বিরাম চিহ্ন এবং স্পেস অনুমোদিত।
-## ধাপ
-১) সমস্ত বিরাম চিহ্ন এবং হোয়াইটস্পেস মুছে এবং সমস্ত অক্ষরকে ছোট হাতের অক্ষরে রূপান্তর করে স্ট্রিংটি পরিষ্কার করুন।
-২) পরিষ্কার স্ট্রিং বিপরীত.
-৩) যদি পরিষ্কার স্ট্রিং বিপরীত স্ট্রিং এর মত হয় তাহলে আমাদের একটি প্যালিনড্রোম আছে।
-
-## উদাহরণ
-
-### একক শব্দ প্যালিনড্রোম
-- নাগরিক
-- স্তর
-- ম্যাডাম
-- রাডার
-
-### একাধিক শব্দ প্যালিনড্রোম
-- মাথা নাড়বেন না।
-- আমি করেছি, তাই না?
-- আমার জিম
-- একজন মানুষ, একটি পরিকল্পনা, একটি খাল - পানামা
