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.

//#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
	int main(){
     int A1, A2, A3;
      int A;
      scanf("%d%d%d",A1 ,A2 ,A3);
      A = A1 + A2 + A3;
      if(A >= 22){printf("bust");}
      else{printf("win");}
      return 0;
    }
