package main
import "fmt"
func main() {
var stringSet map[string]interface{} = make(map[string]interface{})
stringSet["apple"] = nil
stringSet["orange"] = nil
stringSet["cherry"] = nil
// O(1) vs O(n). Only matters for large lists
if _, ok := stringSet["apple"]; !ok {
fmt.Println("apple not in stringset")
if _, ok := stringSet["banana"]; !ok {
fmt.Println("banana not in stringset")
