This project was bootstrapped with Create React App.

Below you will find some information on how to perform common tasks.

Folder Structure

After creation, your project should look like this:

my-app/
  README.md
  node_modules/
  package.json
  public/
    index.html
    favicon.ico
  src/
    App.css
    App.js
    App.test.js
    index.css
    index.js
    logo.svg

For the project to build, these files must exist with exact filenames:

• public/index.html is the page template;
• src/index.js is the JavaScript entry point.

You can delete or rename the other files.

You may create subdirectories inside src. For faster rebuilds, only files inside src are processed by Webpack.
You need to put any JS and CSS files inside src, otherwise Webpack won’t see them.

Only files inside public can be used from public/index.html.
Read instructions below for using assets from JavaScript and HTML.

You can, however, create more top-level directories.
They will not be included in the production build so you can use them for things like documentation.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

LCD refactor

Objetivo: Crear un programa que imprime números en estilo de una pantalla LCD

Entrada: La entrada contiene varias líneas. Cada línea contiene 2 números separados por coma. El primer número representa el tamaño de la impresión (entre 1 y 10, esta variable se llama “size”). El segundo número es el número a mostrar en la pantalla. Para terminar, se debe digitar 0,0. Esto terminará la aplicación.

Salida: Imprimir los números especificados usando el caracter “-“ para los caracteres horizontales, y “|” para los verticales. Cada dígito debe ocupar exactamente size+2 columnas y 2*size + 3 filas.

Entre cada impresión debe haber una línea blanca.

Ejemplo: Entrada:

2,12345
3,67890
0,0

Salida:
