##Introduction

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f516q7qfc0twgypolo0v.png)

Here our problem says, we are given 2 arrays and have to build a new array using those 2. So, in an array there is two part one is index and another one is value in that index. Here the our new array index and its value is separated in two other array one is nums which consist the index value and another one is index array where we have the index value of the new array.

##Examples

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6aki2c28w05cnbgjvqnx.png)

##Steps
1. Take a for loop and set the index value to arrIndex and array_value to value
2. Check if Same index is arrived before or not using isArrived Method.
3. if true then run a for loop and swap the elements to it right from the index value.
4. insert the value in the index.

##Hints

##JavaCode

```
class Solution {
    public int[] createTargetArray(int[] nums, int[] index) {
        int[] arr = new int [nums.length];
        int arrIndex = 0;
        int value = 0;

        for(int i = 0; i<nums.length; i++){
            arrIndex = index[i];
            value = nums[i];
            if(isAccess(index, arrIndex, nums.length)){
                for(int j = nums.length-2; j>= arrIndex; j-- )
                {
                    arr[j+1] = arr[j];
                }
            }
            arr[arrIndex] = value;
        }
        return arr;
    }
    public boolean isAccess(int []arr, int arrIndex, int length){
        for(int i = 0; i< length; i++){
            if(arr[i] == arrIndex){
                return true;
            }
        }
        return false;
    }
}
```

React and TypeScript together offer a powerful combination for building robust web applications. This post will guide you through creating your first React component with TypeScript, ensuring type safety and enhancing developer productivity.

## Setting Up Your Environment

Before diving into component creation, ensure your environment is set up for React and TypeScript:

```bash
npx create-react-app my-app --template typescript
cd my-app
npm start
```

## Creating a Typed React Component

Let's create a simple `Greeting` component that accepts a `name` prop:

```tsx
import React from 'react';

type GreetingProps = {
  name: string;
};

const Greeting: React.FC<GreetingProps> = ({ name }) => (
  <div>Hello, {name}!</div>
);

export default Greeting;
```

## Understanding Props and State with Types

TypeScript makes managing props and state straightforward. Here's an example of a component with typed state:

```tsx
import React, { useState } from 'react';

const Counter: React.FC = () => {
  const [count, setCount] = useState<number>(0);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
};

export default Counter;
```

## Practical Example: A Todo List Component

Now, let's apply what we've learned to build a Todo List component:

```tsx
import React, { useState } from 'react';

type Todo = {
  id: number;
  text: string;
};

const TodoList: React.FC = () => {
  const [todos, setTodos] = useState<Todo[]>([]);
  const [input, setInput] = useState('');

  const addTodo = () => {
    setTodos([...todos, { id: todos.length, text: input }]);
    setInput('');
  };

  return (
    <div>
      <input value={input} onChange={e => setInput(e.target.value)} />
      <button onClick={addTodo}>Add Todo</button>
      <ul>
        {todos.map(todo => (
          <li key={todo.id}>{todo.text}</li>
        ))}
      </ul>
    </div>
  );
};

export default TodoList;
```

You've now stepped into the world of typed React components with TypeScript. By integrating TypeScript into your React projects, you'll enjoy a more structured development process, easier debugging, and improved code quality. Keep experimenting with different component structures and TypeScript features to deepen your understanding.

S01E03: Donations, Mastodon, Speakers
Tags: webdev, eventsinyourcity, buildinpublic, opensource
Published: 2024-02-28 15:23:22

## Registrations

We replaced the plain old Google form with a free subscription to [ti.to.](https://ti.to/)

Even though the name brings terrible memories, the service is impressive. Every attendee can get a free ticket and a spot at the event. It's also easier for us to manage it via a usable interface. Currently, we have 30 people registered, which lands us at 30% of our capacity.

## Donations

Organizing such an event has its downsides. Most of the time is money. Even though we got a small budget from our savings, we decided to open a donation effort to see if the community could help us cover the expenses transparently. [We subscribed for Ko-Fi, and our page is here.](https://ko-fi.com/howcamp)

## Speakers

We agreed with five people already to come and talk at our event. More info about them is available on the [How.camp page](https://how.camp/#speakers), and we will have a separate article on that topic soon.

## Website stats

We used a privacy-respecting service called [liteanalytics.com](https://liteanalytics.com) to keep an eye on who is visiting our site and from where so we can focus more on creating targeted content.


![statistics chart showing numbers](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dms0gx4w5uhtd5wpb12s.png)

## Press-release

We decided to publish a press release using EIN services. [Here is the copy we sent out](https://www.einpresswire.com/article/689953526/gabrovo-will-become-the-summer-capital-of-the-open-source-in-bulgaria). We expect limited attention because nothing is super newsworthy in our event. We got a few back-links and tons of spam calls.



## Mastodon

As a reminder, our mastodon account is [@howcamp@fosstodon.org](https://news.how.camp/@/howcamp@fosstodon.org) We have a small but steady trend up, and now we have 25 followers, compared to 19 last week.


## Blog/News
We decided to invest some time in creating [a blog for the event.](https://news.how.camp) We are using the write.as platform for this. It works well. We noticed a slight delay on publishing the content is we are using a custom subdomain.

Thanks for reading this!

Functions and Methods in Go
Published: 2024-02-28 15:10:03

# Functions and Methods in Go

Go is a powerful programming language that allows developers to create efficient and scalable software. One of the key features of Go is its support for functions and methods, which enable developers to organize their code into reusable blocks.

## Functions

In Go, a function is a self-contained block of code that performs a specific task. It can be called from anywhere in the program, making it easy to reuse code and improve modularity. Here's how you can define and use functions in Go:

```go
func add(a int, b int) int {
    return a + b
}

func main() {
    result := add(3, 5)
    fmt.Println(result)  // Output: 8
}
```

In the example above, we defined a function named `add` that takes two integer parameters `a` and `b`. It returns the sum of these two numbers. In the `main` function, we called the `add` function with arguments `3` and `5`, assigning the returned value to a variable named `result`. Finally, we printed out the result using the built-in `fmt.Println()` function.

Go also supports multiple return values in functions:

```go
func divide(dividend float64, divisor float64) (float64,error) {
    if divisor == 0 {
        return 0, errors.New("cannot divide by zero")
    }
    return dividend / divisor,nil
}

func main() {
	result,err := divide(10.0 ,2.0)
	if err != nil{
		fmt.Println(err)
	}else{
		fmt.Println(result) //Output: 5 
	}
}
```

Here's an example where our function returns both quotient (`float64`) as well as an error (`error`) type if division by zero occurs.

## Methods

Methods are similar to functions but are associated with types in Go. They define actions that can be performed on objects of a particular type. This feature enables us to achieve code organization and encapsulation efficiently.

To declare a method in Go, we use the following syntax:

```go
func (s StructName) methodName() {
    // method implementation
}
```

Let's look at an example:

```go
type Circle struct {
    radius float64
}

func (c Circle) area() float64 {
    return math.Pi * c.radius * c.radius
}

func main() {
    circle := Circle{radius: 5}
    fmt.Println(circle.area())  // Output: 78.53981633974483 
}
```

In the example above, we defined a `Circle` struct with a single field `radius`. We then declared an `area()` method for the `Circle` struct that calculates and returns the area of the circle based on its radius using the formula πr².

To call this method, we create an instance of the `Circle` struct named `circle`, and then invoke its `area()` method using dot notation (`circle.area()`). The result is printed to the console using `fmt.Println()`.

Methods can also have additional parameters just like functions if needed.

## Conclusion

Go provides flexible support for both functions and methods, allowing developers to write clean, modular, and reusable code. Functions offer standalone functionality while methods provide functionality specific to types. By understanding how to use these features effectively, you can harness the full power of Go in your programming endeavors.
Multi-Modal Agentic RAG using LangChain
Tags: langchain, agents, openai, rag
Published: 2024-02-28 15:07:49

Explore the world of agents…


![Generated by Dall-E-3](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/66qkuz4yl3bpd7zc2lgi.png)


Most of you might have explored the world of RAG (Retrieval Augmented Generation) to chat with your documents and explored the world of generating images as well. With the capability of function calling now baked into most of the GenAI model providers, the applications are limitless.

## **Agents**

Agents are kind of mini tasks that help you to achieve your specific goals. When multiple agents are combined, they form an indispensable force. Like one program to help you chat with LLMs, make a call to an external API, translate, image generation, etc. Today let’s explore the agents that help us:

1. Chat with any PDF
2. Get recent papers from [paperswithcode](https://paperswithcode.com/)
3. Use Dall-E-3 to generate artistic abstract images

## **Code**

The code is available on [GitHub](https://github.com/sachs7/multi-modal-langchain-chatbot) with well-structured getting started steps.

I will be giving a brief overview of it here:

The technology stack that we will be using is: `LangChain`, `OpenAI`, `paperswithcode` API, `ChromaDB`, and `Dall-E-3`.

Upload your PDF document in the `docs` folder and explore the default agents. If interested, go ahead with creating your agents by adding them to the `services` folder and creating a corresponding tool in the `tools` folder.

The option to execute the code in `Gradio` or `Streamlit` is provided with the default code running as `Streamlit`. I found it difficult to showcase the image/text in `Gradio`, hence the switch to `Streamlit`.

## **Restrictions**

The code is restricted to answer only from the document, if you ask outside of it, the app won’t make a query to the outside world to fetch the response (which in most cases we want if dealing with sensitive documents).

## **Results**

Following are some of the responses from the app, note: the image prompt was taken from [Google](https://blog.google/products/gemini/google-bard-gemini-pro-image-generation/)


![Capabilities](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jn7ru0afzwmlkion9wtv.png)




![Chat with documents](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/oooqn6o825kpmfl0ytsq.png)




![Get the latest paper on <your topic> from Paperwithcode](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qfbh2in77rxblzfijohd.png)




![Image Generation](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0xos4b54xl2j3wuitin0.png)




![Applied Restrictions](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zg8byovse337qs5q5011.png)


Feel free to play around and use it for your own with extended agents!

## **Add-On**

It is always good to know the full trace of your query, I would suggest you try [LangSmith](https://www.langchain.com/langsmith) from LangChain. It provides a whole lot of information on how your query is passed over different stages, and also the cost associated with each of them.

Configuring Firebase with Angular standalone component
Tags: firebase, angular, standalone, typescript
Published: 2024-02-28 14:25:26

Being that by default (using Angular 17 ✨), generating a component using CLI, we get a standalone component and lack of updated documentation from Firebase I decided to publish my implementation of, in this case, a Real-time database connection.

First of, in my `main.ts` I initialized the app and analytics

```typescript
import { bootstrapApplication } from '@angular/platform-browser';
import { appConfig } from './app/app.config';
import { AppComponent } from './app/app.component';
import { initializeApp } from 'firebase/app';
import { firebaseConfig } from '../src/app/environments/environment';
import { getAnalytics } from 'firebase/analytics';

bootstrapApplication(AppComponent, appConfig).catch((err) =>
  console.error(err)
);

const app = initializeApp(firebaseConfig);
const analytics = getAnalytics(app);
```

Then in my environment.ts I added firebaseConfig (That you get after creating a Web App on Firebase Console)

```typescript
export const firebaseConfig = {
  apiKey: 'XXXXXXXXXXXXXXXXXXXX',
  authDomain: 'XXXXXXXXXXXXXXXXXXXX',
  projectId: 'XXXXXXXXXXXXXXXXXXXX',
  databaseURL:
    'XXXXXXXXXXXXXXXXXXXX',
  storageBucket: 'XXXXXXXXXXXXXXXXXXXX',
  messagingSenderId: 'XXXXXXXXXXXXXXXXXXXX',
  appId: 'XXXXXXXXXXXXXXXXXXXX',
  measurementId: 'XXXXXXXXXXXXXXXXXXXX',
};
```

And it's pretty much ready to use, with no extra modules import and configuration. In your Component you first import:

`import { getDatabase, ref, set } from 'firebase/database';`

Then instantiate the database with:

`databaseInstance = getDatabase();`


and mutate data like so:

```typescript
saveData(data) {
    set(ref(this.databaseInstance, `/collection`), {
      date: new Date().toISOString(),
      ...data,
    })
      .then(() => {
        this.isSuccess = true;
      })
      .catch((error) => {
        this.isError = true;
        console.log('Failed to save data: ', error);
      });
  }
```

And that's it, hopefully, it saves someone at least a few minutes of frustration when configuring Firebase with standalone components. If I said something wrong, or you have some extra questions, feel free to write in comments. Cheers🍻
