App 1: Multilingual Greeting
Congratulations! You are now ready to start building your own apps. The best way to learn Shiny is by deconstructing an existing app and rebuilding it from scratch.
In this exercise, you are going to build a Shiny app that allows you to enter your name and select a greeting (Hello/Bonjour), and returns "Hello, Kaelen", when the user is Kaelen. Admittedly, it is a really simple app, but the challenge is you are going to have to code it from scratch! Good luck!!
We have already loaded the shiny package for you. Recall that the four steps to building a Shiny app are: (1) Add inputs, (2) Add outputs, (3) Update layout, and (4) Update outputs.

练习说明
- Add an input to select between greeting types "Hello" and "Bonjour".
- Add an input to enter name as text.
- Your app should print "Bonjour, Kaelen" if the selected greeting type is "Bonjour" and the name entered is "Kaelen".
交互式实操练习
通过完成这段示例代码来试试这个练习。
ui <- fluidPage(
)
server <- function(input, output, session) {
}
shinyApp(ui = ui, server = server)
