You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.go
    path of file: ./repos/build-web-application-with-golang/pt-br/code/src/apps/ch.2.6/switch_type_check
    
    the code of the file until where you have to start completion: package main

import (
    "fmt"
    "strconv"
)

type Element interface{}
type List []Element

type Person struct {
    name string
    age
    
func main() {
    list := make(List, 3)
    list[0] = 1       //an int
    list[1] = "Hello" //a string
    list[2] = Person{"Dennis", 70}

    for index, element := range list {
        switch value := element.(type) {
        case int:
            fmt.Printf("list[%d] is an int and its value is %d\n", index, value)
        case string:
            fmt.Printf("list[%d] is a string and its value is %s\n", index, value)
        case Person:
            fmt.Printf("list[%d] is a Person and its value is %s\n", index, value)
        default:
            fmt.Println("list[%d] is of a different type", index)
        }
    }
}
