	// Create a set using a map with initial values
	set := map[string]bool{
		"apple":  true,
		"banana": true,
		"cherry": true,
	}

	// Access items in the set
	fmt.Println("Items in the set:")
	for item := range set {
		fmt.Println(item)
	}

	// Check if an item exists in the set
	target := "banana"
	if set[target] {
		fmt.Println(target, "is in the set")
	} else {
		fmt.Println(target, "is not in the set")
