## What is Project Euler?

Project Euler is a series of challenging problems that require mathematical and programming skills. Somebody who enjoys learning new area of mathematics, project Euler is going to be a fun journey.

## How to contribute?
- Fork this repository.
- Make a directory with the format `problem_number.problem_statement` in the directory of the language you're solving.
```
For example if you are solving Problem no 1 in java- >
Your solution should be at -> Java/01.Multiples_of_3_and_5/your_user_name.java
```
- Add :white_check_mark: `:white_check_mark:` to the table against the problem you've solved.
- Name the P.R. With the format as `problem_number done in This_Lang`, and Mention the same in the code(File) as a comment `Euler Problem_num`.(**Within the File**)
- While Editing The ReadMe For PR, Use "**No Wrap**" Option { At Top Right Of 'Edit File' Tool On Githtub}
- Send a PR
- [Thanks](#Thanks)

Happy Contributing! 😃

## Thanks

- Thanks to you all who are doing their best in solving the problems, we appriciate your efforts.
- We thank you all for the overwelming P.R that we have recieved, To mantain the quality and response of the P.R we have updated the
[guidelines](#How-to-contribute).
- We are reluctant to change/modify the already merged P.R. to meet the current Guidelines, as that may modify the contributer's title to that file.
- We would appriciate, if all of you could do the necessary modification, hence it won't affect your contribution as per HacktoberFest.
- Keep Up the Efforts.
