The coffee shop writes each customer's name on the cup in capitals so it's easy to read. Write CupName(name) to return the name in upper case. Anything that isn't a letter (like -) stays as it is.
CupName("lily")→'LILY'CupName("Tom")→'TOM'func CupName(name string) stringpackage main
import "strings"
func CupName(name string) string {
// your code here: strings.ToUpper to make name upper case
return name
}
