Implementation of All ▲lgorithms in C++ Programming Language

cpp's Issues

The directory algorithms/data-structures/linkedlist does not cover all the linked list types.

I am creating an issue because... The directory algorithms/data-structures/LinkedList does not cover all the linked list types. I want to contribute. I will add codes for all the linked List types Singly(Linear and Circular) and Doubly(Linear and Circular) Linked List.

How to implement Lucky 🍀 numbers algorithm on C++?

According to AllAlgorithms/python#32 (comment)

Hi @Zxey I liked, but it seems that the algorithm isn't properly implemented.

According to this the following gif:

From 1-100 the lucky numbers should be:

1, 3, 7, 9, 13, 15, 21, 25, 31, 33, 37, 43, 49, 51, 63, 67, 69, 73, 75, 79, 87, 93, 99

This is the link to your implementation repl.it/@abranhe/lucky-numbers-in-python online, I just set the range from 1 - 100.

In a part of the output you will see:

number 17 is not lucky
number 18 is not lucky
number 19 is lucky
number 20 is not lucky
number 21 is not lucky
number 22 is not lucky
number 23 is not lucky
number 24 is not lucky
number 25 is not lucky
number 26 is not lucky
number 27 is lucky
number 28 is not lucky

Where they don't match with the output it should be:

Eg:

• 19 isn't lucky
• 25 is lucky
• 27 isn't lucky
• and so on ...

So this need to be fixed to be merged, I am creating an issue right now, hopefuly we will implement correctly.

After finding this issue on Python I went back again to C++ to double check if the algorithm was ok, but cpp/lucky numbers doesn’t seem right at all.

We need to find the a correct implementation for Lucky Numbers!

add stacks implemented with classes

This issue is:

• A new Algorithm
• An update to an existing algorithm.
• A proposal

see #233 pull reques

Dynamic programming - Memoization

I am creating an issue because...
There is only iterative codes for Dynamic programming.
It would be good to add Memoization (top down) approach as well

Create test for each algorithm

The creation and testing of each algorithm, should be included on was his language repository

Player Sorter for FC24

Make efficient method in dsu

Detailed Description

Link of the file: https://github.com/AllAlgorithms/cpp/blob/master/algorithms/dsu

Context

in all files of dsu, the "find_parent" method is inefficient.

Possible Implementation

We can implement by loop instead of recursion to avoid unnecessary stack and function overhead.

PR created (Reverse LinkedList)

I am creating an issue because I have made a PR for the addition of a new algorithm- Create Reverse LinkedList file #349
Hope you will like it and merge with the repo. Thank you!
