How do i solve this problem in go?

Question

You are making a program for a navigation system.
Your program needs to take a number N as input, followed by N strings, which represent city names.
Store the city names in a slice.
Declare a variadic function route(), which takes its arguments from the slice.
The route() function should output the route, which combines the city names using an arrow. Check the sample input/output for reference:

Sample Input:
3
Boston
Chicago
Washington

Sample Output:
Boston->Chicago->Washington->

Answer 2

package main
import "fmt"

//create the route() function

func main() {
var n int
fmt.Scanln(&n)

var cities []string
//take n strings as input and append them to the slice

//
route(cities...)
}

//Can you solve this code please?

Answer 3

//cities := make([]string, N)
// Or
var cities []string
cities = make([]string, N)
