	"fmt"

	prime "github.com/theTardigrade/golang-prime"

)

func main() {

	var magicNumber int64 = 3

	fmt.Println(prime.Is(magicNumber))   // true

	fmt.Println(prime.Next(magicNumber)) // 5, true

	fmt.Println(prime.Prev(magicNumber)) // 2, true

	fmt.Println("*****")

	magicNumber = 120

	fmt.Println(prime.Is(magicNumber))   // false

	fmt.Println(prime.Next(magicNumber)) // 127, true

	fmt.Println(prime.Prev(magicNumber)) // 113, true

	fmt.Println("*****")

	magicNumber = 2

	fmt.Println(prime.Is(magicNumber))   // true

	fmt.Println(prime.Next(magicNumber)) // 3, true

	fmt.Println(prime.Prev(magicNumber)) // 0, false

	fmt.Println("*****")

	magicNumber = 1_000_000_000_000

	fmt.Println(prime.Is(magicNumber))   // false

	fmt.Println(prime.Next(magicNumber)) // 1000000000001, true

	fmt.Println(prime.Prev(magicNumber)) // 999999999997, true
