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 have add a new file named perfectNumber.cpp in M-MathematicalAlgorithms

Info

I have developed program that check if the number is perfect or not by get all the divisors then get the sum of them
if the sum equal the number then the number is perfect number

Algorithm

step1 - take from user a number
step2 -get all numbers that can be divided
step3 -

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
