HackTrack Chrome Extension

dee-ksha — Sat, 19 Feb 2022 12:43:13 +0000

HackTrack is a Chrome extension I created during the UAcelt Winter of Mentorship 2.0 program. I tend to forget the deadlines or important dates of major Hackathons I'm interested in and sometimes I just bookmark the links of the application forms to fill them out later after careful consideration of the requirements and often forget to check them out which leads to me missing out on the programs.

This is where HackTrack comes in handy as I can always see it on my Browser Tool bar. Through this I can keep a check on upcoming Hackathons and their important dates.

I can cross the tasks out after registering for them and then delete them from the list as and when I'm done with them. The refresh button at the top lets me clear all the items from the list and start anew.

In future I plan on adding multiple input fields for date and the link to the forms or websites or the programs to make it more convenient. I would also like to add the feature to drag and drop the items according to their priority.

In the first few weeks of the mentorship program I learnt about git and github basics, working with APIs and JSON.

The first Chrome extension I created during this program is called 'Joke' which displays a random joke on each click.

Afterwards, with the help of my mentor I put together an extension called 'Dictionary' which fetches the meaning, pronunciation, example and synonym of the word we want to search.

I had fun during the course of this program and learnt networking and interpersonal skills along with the technical skills. Also, do tell me if you have any suggestions or if you would like me to add some features, please do let me know in the comments. Constructive criticism is appreciated.

How to insert a node in a Circular Linked List? C++

dee-ksha — Wed, 24 Nov 2021 09:15:35 +0000

A Circular Linked List is a variation of Linked List where the first and the last node are also linked to each other, forming a circle. In an ordinary Linked List, the next pointer of the last node points to NULL but in the case of a Circular Linked List, the next pointer of the last node points to the head of the list.

The Circular Linked List makes the traversal in the list more efficient as any node can act as a starting node and the whole list can be traversed starting from any node. It also makes performing operations like enqueue and dequeue easier as the last node and the head node are connected.

Insertion at the head of a Circular Linked List

#include <bits/stdc++.h>
using namespace std;
// Linked List Node
class Node {

public:
    int data;
    Node* next;
    // Constructor
    Node(int info)
    {
        data = info;
        next = NULL;
    }
};
// Inserts at the head of the list
void insertAtFront(Node*& head, int info)
{
    Node* newnode = new Node(info); // Create a new node

    if (head
        == NULL) // if the list has not been created yet
    {
        newnode->next = newnode;
        head = newnode;
        return;
    }
    Node* temp = head; // Creating a pointer for traversal

    while (temp->next != head) //traversing until the first node is encountered again
    {
        temp = temp->next;
    }
    temp->next = newnode;
    newnode->next = head;
    head = newnode;
}

Insertion at the end of the List

#include <bits/stdc++.h>
using namespace std;
// Linked List Node
class Node {

public:
    int data;
    Node* next;
    // Constructor
    Node(int info)
    {
        data = info;
        next = NULL;
    }
};

// Inserts at the tail of the list
void insertAtEnd(Node*& head, int info)
{

    if (head == NULL) {
        insertAtFront(head, info);
        return;
    }

    Node* newnode = new Node(info);
    Node* temp = head; //Creating a pointer for traversal

    while (temp->next != head) //traversing until the first node is encountered again
    {
        temp = temp->next;
    }

    temp->next = newnode;
    newnode->next = head;
}

Insertion in the middle of the Circular List follows the same approach as it would in an ordinary Linked List. You can check it out here.

Following is a complete program that uses both of the above methods of insertion in a Circular linked list and displaying it.

#include <bits/stdc++.h>
using namespace std;
// Linked List Node
class Node {

public:
    int data;
    Node* next;
    // Constructor
    Node(int info)
    {
        data = info;
        next = NULL;
    }
};
// Inserts at the head of the list
void insertAtFront(Node*& head, int info)
{
    Node* newnode = new Node(info);

    if (head == NULL) {
        newnode->next = newnode;
        head = newnode;
        return;
    }
    Node* temp = head;

    while (temp->next != head) {
        temp = temp->next;
    }
    temp->next = newnode;
    newnode->next = head;
    head = newnode;
}
// Inserts at the tail of the list
void insertAtEnd(Node*& head, int info)
{

    if (head == NULL) {
        insertAtFront(head, info);
        return;
    }

    Node* newnode = new Node(info);
    Node* temp = head;

    while (temp->next != head) {
        temp = temp->next;
    }

    temp->next = newnode;
    newnode->next = head;
}

void displaylist(Node* head)
{

    Node* temp = head;
    do {
        cout << temp->data << " ";
        temp = temp->next;
    } while (temp != head);
    cout << endl;
}

int main()
{
    Node* head = NULL;
    insertAtEnd(head, 1);
    insertAtEnd(head, 2);
    insertAtEnd(head, 3);
    insertAtEnd(head, 4);
    insertAtFront(head, 5);
    insertAtFront(head, 6);
    displaylist(head); 
}

YouTube Channels and resources for Engineering Students

The concept of education has changed drastically in the recent years. With the rise of internet and technology you don't have to be present in the classroom to learn something. You have access to quality education anytime and anywhere.

With the ocean of resources you might feel confused about where to start from or which program to choose to develop your skills. Here is the list of a few resources which helped me learn and grow.

freeCodeCamp: If you want to get hands-on practice with the skills you're learning then you should definitely check out this platform. It provides you with a code editor and output screen along with the informational content so you can learn the concepts and simultaneously apply them as well. There are various subtasks in every course and after the completion of these subtasks, you can test the skills you learnt by working on some example projects which come with problem statements. They also provide certification after the successful submission of the projects. They also have a YouTube channel covering a plethora of courses taught by instructors around the globe. They are a Non-Profit organization with a supportive community which has helped millions with their interactive coding lessons, articles and videos in exploring new fields.
Neso Academy: I recommend this channel to everyone who is currently preparing for GATE, their university exams or just wanting to learn about basics of Computer and Operating System. Their videos are beginner friendly and have detailed explanation about the concepts making them easier to understand and retained. Along with the core computer science subjects, this channel also offers amazing content about Analog and Digital Electronics and Instrumentation.
Code with Harry: This channel has playlists covering a wide variety of fields, be it any programming language, web development, app development, GUI with Tkinter,Data Structures & Algorithms, Machine learning, etc. One thing I liked about this channel apart from the amazing content is that the notes and the links to the code are provided in the description which come handy when you want to revise the session.

Following are some of the DSA and competitive programming playlists that I found really helpful

• Competitive Programming/DSA Course | Hindi By luv

• C++ Full Course | C++ Tutorial | Data Structures & Algorithms By Apna College

• Dynamic Programming Playlist | Coding | Interview Questions | Tutorials | Algorithm By Aditya Verma

• Data Structures and Algorithms By: Jenny's lectures CS/IT NET&JRF

These are some of the resources which I found useful, if you have other recommendations, please drop them in the comments. I would love to check them out. Let's keep learning and growing together!

Web Development or App Development? Where to start?

dee-ksha — Fri, 05 Nov 2021 03:09:19 +0000

One common question that I have seen my peers ask is whether to start their development journey with Web development or App Development. Beginners in tech are often confused about the right choice to make because there is a wide variety of options and areas to explore.

Web Development and App Development are emerging sectors for developers. Both the fields have their own benefits and complexities and require different skills, different markets and diversified usage. Therefore, there is no model answer to what you should be starting first.

But according to my own experience I would suggest to go for web development first due to the following reasons:

• App development is the fastest leading trend but web development is something that will never disappear. The web is the best platform for acquiring new users and building a brand. Nearly all brands that opt for an app-based approach build a website too in order to market and promote their app.

• Web development is slightly easier to understand and apply than app development and it also lays down a framework which helps in many areas of app development as well like making an API, using different database technologies, working with server and backend etc.

Whichever route you choose, you'll learn something great and there's no better time to kickstart your development journey than now. So, get yourself started now. Good luck!
