This issue is up for Python implementation.

Egg dropping refers to a class of problems in which it is important to find the correct response without exceeding a (low) number of certain failure states.

Is your feature request related to a problem? Please describe.
In a toy example, there is a tower of n floors and an egg dropper with m ideal eggs. The physical properties of the ideal egg are such that it will shatter if it is dropped from floor n^n or above, and will have no damage whatsoever if it is dropped from floor n^-1n or below. The problem is to find a strategy such that the egg dropper can determine the floor n^*n in as few eggs drop as possible.

Describe the solution you'd like
This problem has many applications in the real world such as avoiding a call out to the slow HDD or attempting to minimize cache misses or running a large number of expensive queries on a database.

Hashing related codes include extensive use of HashMap and HashSet Collections of Java. They reduce the time complexity of programs significantly due to the constant time lookup feature. Hashing has always been in the forefront of programming interview questions. I have a bunch of programs and would love to contribute so as to help others.

Hi Everyone!

I hope you all are doing well. As you might be aware of the fact that a lot of spamming is happening this year and it disturbed the whole open source community. The officials have changed the way hactoberfest will work this year. Major changes include:

• Repository classified with the ‘hacktoberfest’ topic: Now onwards, only the repositories which have this topic will be eligible for hacktoberfest contribution.
• The pull requests will also need to be merged, approved by a maintainer, or labeled as ‘hacktoberfest-accepted’ in order to qualify. The deadline for completions, merging, labeling, and approving is November 1.

For reading the full update, head over to this link.

Thanks!

Welcome Everyone!

We are overwhelmed with the response from your side and we would merge/review all your codes but here are some things I have noticed till now:

• Most/ Maximum of you are not following contribution guidelines
• Not filling the issue and PR templates
• Not commenting in your code
• Pushing code from the master branch (most annoying thing for me!)
• Doing multiple tasks other than assigned ones

I know this is new for you and that's why Hacktoberfest was started. To teach people what open source contribution is all about, it's norms and guidelines to follow while contributing. This is a fairly small attempt to teach you how you should contribute to bigger projects where your PRs are not attended even for years. Here is the future plan enforced for PRs after this announcement:

• Any PR without any assigned issue, incompletely filled template, or even without a description will be straight away rejected with an invalid label. You may/may not be aware of this fact that invalid labeled PRs are not counted in the hactoberfest counter.
• Please create issues before making PR and most importantly, wait for them to be assigned to you and then make your PR
• Low-quality codes will be straight away rejected.
• Update the Readme of the language folder with your program entry properly. It makes it easier for us to maintain the codebase.
• PRs which are not updated after the reviews/requested changes within 7 days will be considered as invalid and spam.
• Please take the reviews made by us seriously, we are correcting your code only for you, we don't have any personal issues with anyone, all are equal for us!
  Note: Issues are assigned on first come first basis, do check if the issue or language implementation is not claimed by anyone else

Fork the repo, create a separate branch in your forked repo, get issues assigned, work on them, make PR, get your code reviewed, and get it merged - The whole process in one line!

For language issues confusion here is the breakdown:

• This repo is to welcome beginners to Github and the opensource community by helping them learn how to make their first PR and contributions to open source!

• That said, only high-quality contributions and pull requests that add value to Open Source projects are part of the core values of Hacktoberfest. There's a high chance that repositories like this one that allows users to gain a headstart for completing the challenge faster might get excluded from the Hacktoberfest.

• So I highly recommend you to contribute in a meaningful way in this repository and other Hacktoberfest issues.

⚠️ Please refrain plagiarising code for the sake of pull request. We highly discourage it

I would like to add Graph traversal algorithms which include Breadth-First Search (BFS) & Depth First Search (DFS), Cycle Detection Algorithm as well as Shortest Path Detection Algorithms which include Dijkstra Algorithm & Bellman-Ford Algorithm.

Is your feature request related to a problem? Please describe.
Yes, all these algorithms are related to basic graph problems.

Describe the solution you'd like
These algorithms have many applications which are as follows.

1. Computer games - finding the best/shortest route from one point to another.
2. Maps - finding the shortest/cheapest path for a car from one city to another, by using given roads.
3. May be used to find the fastest way for a car to get from one point to another inside a certain city. E.g. satellite navigation system that shows to drivers which way they should better go.

Anyone can write code to make things work, but your code should be good enough so that other developers can understand it. Not only it makes your code looks neat, it also ensures your code has less errors. It can help you debug any error and also enhance the existing logic quite easily.

You can also include the best practices for various languages.

For example

• How the variable names should look like
• What should be class and method names
• Number of characters before you switch a new line
• Maximum Cognitive Complexity in a method.
• Have meaningful method and variable names, so the reader knows what the code does and why is it there.

Though this can be language specific, but what I feel is learning correctly from the beginning is much more easier than changing your old coding habits.
Writing a neat code is something that will help you stand out of other developers as well in this competitive world.
