Problem Statement

Given are three integers A_1, A_2, and A_3.

If A_1+A_2+A_3 is greater than or equal to 22, print bust; otherwise, print win.

Constraints

1 \leq A_i \leq 13 \ \ (i=1,2,3)

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A_1 A_2 A_3

Output

If A_1+A_2+A_3 is greater than or equal to 22, print bust; otherwise, print win.

Sample Input 1

5 7 9

Sample Output 1

win

5+7+9=21, so print win.

Sample Input 2

13 7 2

Sample Output 2

bust

13+7+2=22, so print bust.

Solution in C (Clang 3.8.0) (judge verdict: Accepted)

#include <stdio.h>
int main(void){
  int a[3];
  int i,sum;
  sum=0;
  for(i=0;i<=2;i++){
    scanf("%d",&a[i]);
    sum+=a[i];
  }
  
  if(sum<=21)
    puts("win");
  else
    puts("bust");
}
