You can put up a problem yourself.
You can even contribute a project made by you!
Please read this issue click here for more information.

New to github? No problem :) Refer to these resources 🆕

Steps to put up an issue:📑

First let's see when should you create an issue?

If you want to contribute a question or project.
If you have a better solution to an existing solved issue.

To create an issue:

Click on the Issue button at top of the page:

Click new issue and fill up the details!

Note: Issues must clearly mention what they are addressing, if a problem is being put up then explain it using an example.

Get contributing🤩

Note: One must read CODE_OF_CONDUCT before starting work on any issue

First things first, In order to contribute you have to create a Pull Request from your forked repo which is a remote clone of this upstream repository.

Click this button at the top of screen to fork this repo, don't forget to star the repository!:
Now head over to the forked repository and copy the clone HTTPS URL:
Next up clone the forked repo on to the local machine using:

git clone <copied-fork-link>

Run these command to add remote origin

git remote add origin <The url of forked github repository>

If this command give message like git remote already exist then run this command

git remote set-url origin <The url of forked github repository>

It is critical to keep your forked repository in sync the upstream repository so merge conflicts can be avoided:

git remote add upstream https://github.com/ShivamYadav-Coding/hacktoberfest-2021.git
git fetch upstream
git pull upstream main

Create a seperate branch to work on:

The branch name must be selected according to the issue

git checkout -b <branch-name>
Contributors must follow the directory structure guidelines:
- All files must be kept in a directory.
- Directory name must resemble the issue assigned.
- Based on the language used, create a directory inside the language directory.
- Example: If I am writing in Python I will create a directory inside Python directory.
- In case a project is being contributed make sure to add the files inside a directory(name according to project) which in turn must be placed inside the Projects directory.
- Changes done by you will not affect existing structure of the project.
- Add a README.md with your name and link to github profile using [your-name](link-to-profile)
After the contribution work is ready go ahead and add it to staging area:

git add -A
Now it is time to commit your changes and sync these changes to forked repo:

git commit -m <your_message>

git push origin <branch-name>
Issue a pull request from forked repo to this repo:
- Head over to Pull Request tab in the forked repo and click on New Pull Request
- Verify base and head repository name and branch names.
- Fill in the title and provide a concise description.
Wait for respose on the PR. Congratulations you just contributed to open source!

Multiply 2 matrices using python

Please assign me to multiply 2 matrices written in python

Power of two or not.

Given a number n. print "YES" if it is a power of two otherwise print "NO".

Example-
INPUT -
32
OUTPUT-
YES

INPUT-
3
OUTPUT-
NO

Given a number N. Your task is to check whether it is fascinating or not.
Fascinating Number: When a number(should contain 3 digits or more) is multiplied by 2 and 3 ,and when both these products are concatenated with the original number, then it results in all digits from 1 to 9 present exactly once.

Example 1:

Input:
N = 192
Output: Fascinating
Explanation: After multiplication with 2 and 3, and concatenating with original number, number will become 192384576 which contains all digits from 1 to 9.

Example 2:

Input:
N = 853
Output: Not Fascinating
Explanation: It's not a fascinating number.

Repository is open for contribution now :partying_face:

This repository is now open for contribution.

Guidelines -

Everyone has to open an issue regarding what program or project they want to add inside repository before making pull request for it.
If the issue is for a new program then they need to comment under that issue about which language they want to use for that program( other person could also comment). Then that issue will be assigned to that person for that language. Any person could contribute upto two program in different language for a particular issue.
Please add folder of your projects inside project folder and programs inside its appropriate folder according to language used.
Example for a issue click here

Performing a Merge sort algorithm using JavaScript

Hey, I would like to add the code of performing Merge Sort Algorithm using JavaScript. Since, the sorting algorithms present in the JavaScript repo (currently), are not that efficient in terms of Time Complexity. I would like to add the code, so can you please assign it to me. Also, it will be helpful if you're adding the Hactoberfest Tag for this issue. Thanks !

# Alert !!!

Please don't contribute to this repository anymore. Hacktoberfest has excluded this repository because of the violation of values.
Which means no pull request to this repository will be counted for Hacktoberfest. The reason for this is the acceptance of DSA programs. The acceptance of DSA program worked fine till last year but it seems that Hacktoberfest started to exclude those repositories which accepts DSA programs from this year since it seems like a shortcut.

I am sorry for all of this. Since no one knows that this could happens there are many more repositories who follow the same strategy to accept DSA programs to help the beginners.
I was little skeptical to accept DSA programs but still i did because i thinks that beginners who aren't much familiar with development will also get to contribute and learn to how use Github and make a pull request. And there are no issues with this till last year.

It seems that Hacktoberfest wants people to contribute to a repository which builds some sort of product (example :- website or app). So from now onwards please refrain from contributing into any repository which accepts DSA programs.

Reverse a linked list

Given pointer to the head node of a linked list, the task is to reverse the linked list. We need to reverse the list by changing the links between nodes.

Examples:

Input: Head of following linked list
1->2->3->4->NULL
Output: Linked list should be changed to,
4->3->2->1->NULL

Input: Head of following linked list
1->2->3->4->5->NULL
Output: Linked list should be changed to,
5->4->3->2->1->NULL

Input: NULL
Output: NULL

Input: 1->NULL
Output: 1->NULL

Write this program with your choice of language and inside appropriate folder. For example if you are writing this program in c++ then make sure that file of this program is in cpp folder.

Big update!!

Big update: Only pull regarding projects will be accepted from 6 october. Pull request with DSA program will not be accepted.
This update is made keeping in mind hacktoberfest policies.

Coin Change Problem - C language

Given a value N, if we want to make change for N cents, and we have infinite supply of each of S = { S1, S2, .. , Sm} valued coins, how many ways can we make the change? The order of coins doesn’t matter.
For example, for N = 4 and S = {1,2,3}, there are four solutions: {1,1,1,1},{1,1,2},{2,2},{1,3}. So output should be 4. For N = 10 and S = {2, 5, 3, 6}, there are five solutions: {2,2,2,2,2}, {2,2,3,3}, {2,2,6}, {2,3,5} and {5,5}. So the output should be 5.

Hello @ShivamYadav-Coding sir, kindly allow me to work on this issue in C language, and assign me this. Also please add the tags for hacktoberfest. Thank you.
