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 :

Proposed Changes

Added a file comparing two strings .
Most string comparison algorithms compare the strings character by character. C++ provides us some built in operators like == and != to compare strings along with strcmp and compare functions.

The mentioned file needs to be re-written. There is no concept of overflow in Circular Queue as it wraps up. What I mean is:
Test Driver Code:
public static void main(String[] agrs) {
CircularQueue q = new CircularQueue(5);
q.insert(10);
q.insert(20);
q.insert(30);
q.insert(40);
q

Since a folder for Codewars_problems has been created, more problems and solutions can be added from Codewars✨

Preferred difficulty level: Easy-Medium/hard (please refrain from adding too beginner/trivial questions)

Dado um número de CPF, o algoritmo deve validar se o número dado é um número válido.
Detalhes de como o cálculo funciona pode ser encontrado aqui

Descrição da Função
A função deve ser capaz de receber o CPF como Integer ou String.

Se for String, deve retirar pontos para manter somente os números.

Em seguida, deve fazer os cálculos da validação
