Algorithm

We have a lot of is_prime (or similar) functions: https://github.com/TheAlgorithms/Python/search?p=4&q=is_prime, https://github.com/TheAlgorithms/Python/search?q=isPrime, data_structures/hashing/number_theory/prime_numbers, etc. Shall we use one common function for that exactly identical

Description

Currently, there are many CodeQL warnings. LGTM is marking our code quality as B. We need to get it higher (link: https://lgtm.com/projects/g/TheAlgorithms/C-Plus-Plus/alerts/?mode=list).

Expected behavior

We should fix all the CodeQL/LGTM warnings.

Actual behavior

LGTM is reporting 7 alerts, which marks our quality code as B.

Possible fix

Fix all the CodeQ

What about create a design pattern directory with the most popular design patterns examples?
We can create some rules like: have to be an explanation about the design pattern, the structure and one real world example.
The directory can be:

(folder) Design Patterns
-- (folder) Abstract Factory
-- -- AbstractFactory.js
-- -- AbstractFactoryTest.js
-- -- REAME.md

I can send some :

🚀 Feature Proposal

Adding leading zero in the question number will be an awesome feature for file explorer to sort files by the name.
