 package main

 import (

     "fmt"
 )

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

     for {
         var input int
         fmt.Scanf("%d\n", &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
