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: 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)

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.
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.
