Chapter 2.7 Code Example is Incorrect

[SErvin4390]

In the book, the example is shown as

`func location(name, city string) (region, continent string) {
switch city {
case "New York", "LA", "Chicago":
continent = "North America"
default:
continent = "Unknown"
}
return
}

func main() {
region, continent := location("Matt", "LA")
fmt.Printf("%s lives in %s", region, continent)
}`

But, the Go Playground shows

`package main

import "fmt"

func location(city string) (region, continent string) {
switch city {
case "Los Angeles", "LA", "Santa Monica":
region, continent = "California", "North America"
case "New York", "NYC":
region, continent = "New York", "North America"
default:
region, continent = "Unknown", "Unknown"
}
return
}

func main() {
region, continent := location("Santa Monica")
fmt.Printf("Matt lives in %s, %s", region, continent)
}
`

The Playground seems to be more correct than the code shown in the book text.
