UPDATE: If possible only submit solution to problems which doesn't exists in this repository.

As of now, we are only accepting PRs with one algorithm in it as it is easier to review one file at a time.
Feel free to open PR for whichever problem you have solved provided the answer is correct.

Anyone reading this can join and open PRs as well. We accept multiple solutions to a problem as everyone has their own approach to problem-solving but it should be their own and unique compared to other solutions.

NOTE: Please give us time to review as there are so many to go through. If possible submit one PR at a time and when that is merged provided it passes all the automatic tests, you can submit another PR. Also, please read the contributing guidelines before opening a PR.

One step at a time

Please follow the points mentioned below regarding Project Euler solutions. This is done to maintain consistency throughout the directory and to run this script which checks all the solutions:

• There should be a function called solution() which, when called without any arguments, returns the answer to the problem.
• If you wish to include parameters for the solution() function then the default value for the parameters should be the question input so that when the function is called without any arguments, it returns the answer to the problem.

Example:

def solution():                               # function without any parameters
    # ... calculations ...
    return answer

# If we call this function without passing any arguments, it will return the answer
solution()  # -> answer

def solution(input: "default value"):         # function with parameters having default value
    # ... calculations ...
    return answer

# If we call this function without passing any arguments, it will return the answer
solution()  # -> answer

For problems which needs to work with large data, put the data in a separate file and import it.

Where can I get the problems from?

Hope this helps

Thanks it helped🙂

I would love to join and contribute. Project Euler was always fun to me back in college :)

Hi,
When there is a program for which input is presented as a file, how should the input be coded?
Should it be hardcoded in the file or should it be reading from a file relative to the directory?

@berry-thawson Please refer to problem_54#L367-L369

import os  # with other imports
...

def solution():
    script_dir = os.path.abspath(os.path.dirname(__file__))
    <file_name_without_extension> = os.path.join(script_dir, "<file_name>")
    with open(<file_name_without_extension> , "r") as file_hand:
        # ... your code ...

• Instead of <file_name> add the name of the file you want to import.
• Instead of <file_name_without_extension> add the variable name which is descriptive. If possible choose the name as the file name but without the extension.
• Then using with do whatever you want to do with the contents of the file.

I hope this clears your doubt. If you still have any problem, don't hesitate to ask.

Thanks @dhruvmanila
