Totally we have received more than 300 submissions and we only choose 120 people for 3 program.

40 people for each program.

It was actually very difficult to choose people.

Major factors are

- people who tells us why they want to join the program.
- people who choose one program only and tell us why.

We saw a lot of people who choose 3 program with no explanation and we really don't know which program is good for them so we didn't select those.

We will post the next phase as soon as we finish the current phase.

Please understand that it was really not an easy task for us to go through all the submissions but we took time and go through it.

Thank you very much for your interest surely we are all doing what we best can here 🙏.

Invitation has been sent out to Programming with Python mentorship members.

Please be respectful if you are not selected that is okay you can get the same thing here also.

Keep in mind that am doing this out of my free time.

I am stressing myself here to help. Never asked you for money so whether you are selected or not please keep in mind that we all are trying to learn here.

Thank you for understanding

Today @codenight VC is not there so for anyone interested to chat join here

Google Foobar progress

Honestly speaking the challenge was tougher than I thought it took me couple of days to solve Level 3 🥵.

It sweats the shit out of me 😂.

Anyway level 4 next I don't know how am I gonna make time for it.

Enjoy felas

🌟 Hey Coders! Let's Build This Repo Together! 🌟

I was in need of developers, and finding them was a challenge. Please help by filling out the details and create a Pull Request (PR) to add yourself as a developer. Don't forget to star the repository!

🚀 Repository Link: [Codenight Developers Repository](https://github.com/chapimenge3/codenight-developers)

Let's collaborate and make this repository a hub for talented developers! Your contributions are valuable. Thank you! 🙌

Everything starts here

Gosh it was the best and we have come a long ways.

My all time advice to anyone is TO HAVE PATIENCE (SABIR).

Let's focus keep up the positive energy we got here.

2024 is our year let's crush it.

We have now got our own org on github.


Check it out give us a follow and all content will be posted there

Ever heard of B-Tree Data structure?

They are one of the most popular and common data structure used in database indexing.

You might ask what is database indexing? It's a way of storing values in a very particular way so that searching them will give you a very fast responses (ofc there is more to it.)

Coming back to B-Tree, most database including Postgres and MySQL uses to index thier rows.

Example is All primary key is index by default. That is why if you use always Primary key to search/retrieve from database it is extremely fast.

When I say extremely fast let's put it in number, shall we?

Let's say you have 1 Million row in your Table. If you search using primary key it will only look maximum of Log(1,000,000) = 19.93 ~ 20

This means it only look up 20 items and then it will retrieve the value.

But if you look by something else which example is by name? It will have to look all 1,000,000 on worst case.

Is it not insane 🤯 ?

Seriously it is such an amazing algorithm and data structure itself.

That is why database uses B Tree for indexing.

Anyways it is amazing to explore the space of data structure and algorithms in real world actions.

What is your favourite data structure and why ?

Another good news @chapimenge also want to sponsor additional 10 students 🥰 and I will give priority to those who has been following him on his channel https://t.me/codewizme and also on his LinkedIn https://www.linkedin.com/in/chapimenge?utm_source=share&utm_campaign=share_via&utm_content=profile&utm_medium=android_app

Only for 10 people who actually is in NodeJS.

Giving away course access to 10 people only.

Let's Talk about Queue Today!

Queue is a data structure that follows the FIFO (First In First Out) principle. It is similar to a line of people waiting for a Taxi(which is literally YOU waiting for addis abeba Bus/Taxi). The first person to get in the line is the first person to get in to the Taxi that takes you out of Addis Abeba(Who knows may be wede hayat), and if you are the last person well Good Luck! You will have to wait for the next Taxi.

Queue has two main operations: enqueue and dequeue.

- Enqueue adds an element to the end of the queue
- Dequeue removes the element from the front of the queue.

Always remember that the first element added to the queue will be the first element to be removed from the queue.

Applications of Queue:

- CPU scheduling, Disk Scheduling
- When data is transferred asynchronously between two processes.The queue is used for synchronization. For example: IO Buffers, pipes, file IO, etc
- Network Protocols such as TCP/UDP use queues to hold data packets until they are read by the receiving program.
- Web servers respond to requests in the order they are received (first come first serve) using queues.
- Breadth First Search uses queues to store nodes which are to be explored.

Next time you are waiting for a Taxi, think about Queue and how it works.

We will discuss about Priority Queue in the next post.

I guess no free time soon 😭

Good Morning my people

Advice of the day is going to be

DON'T COMPARE YOURSELF TO ANYONE AND FEEL BAD.

YOU HAVE YOUR OWN UNIQUE PATH FOLLOW IT AND TRUST THR PROCESS. DO YOUR BEST AND LET IT BE HAPPEN

You might see some people with very successful career and feel bad. Trust me everyone see other people can be feel bad but the difference between you and the successful people are they don't compare themselves to others people and feel bad.

Don't create a space for this kind feeling that slows down your journey.

So Let's do our best and let God do it's things. Trust the process.

Following up with our Queue concept, We will try to see Priority Queue in this short post.

Priority Queue is an extension of queue in which each element is associated with a priority value and all the elements are arranged in the queue either in increasing or decreasing order based on their priority. If two elements have the same priority, they are served according to their order in the queue.

Usually higher priority elements are served first(based there is a time you might need the lower priority element to be served first).

Efficient way to implement Priority Queue is using Heaps(We will see at some point in the future), or Binary Search Tree.

Example: PQ(Priority Queue)

PQ.push(3)
PQ.push(10)
PQ.push(1)

PQ=(10, 3, 1) sorted by priority in this case increasing order.

Time Complexity:
- Insertion: O(Log(n))
- Deletion: O(Log(n))
- Get Highest Priority: O(1)

Applications:
- CPU Scheduling in Operating Systems.
- Graph algorithms like Dijkstra’s shortest path algorithm, Prim’s Minimum Spanning Tree, etc.
- All queue applications where priority is involved.
- Data compression in Huffman code

Language with built-in Priority Queue:

- C++ STL

#include <bits/stdc++.h> // header file includes every Standard library
// rest of the code is same as the one in the previous post

int main(){
    priority_queue<int> pq; // max heap
    priority_queue<int, vector<int>, greater<int>> pq; // min heap
    return 0;
}

- Java

import java.util.*;

PriorityQueue<Integer> pQueue = new PriorityQueue<Integer>();

- Python

import queue

q = queue.PriorityQueue()

And that's it for today, I hope you enjoyed it and see you next time
