    "fmt"
)


func main() {
    //var n int 
    n := rand.Intn(100)

    for {
        var input int 
        fmt.Scanf("%d
", &input)
        flag := false
        switch {
        case input == n:
            fmt.Println("you are right!")
            flag = true
        case input > n:
            fmt.Println("bigger!")
        case input < n:
            fmt.Println("less!")
        }

        if flag {
            break
