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>
//#include<conio.h>
int main(){
  int A1;
  int A2;
  int A3;
  int result;
  scanf("%d",&A1);
  scanf("%d",&A2);
  scanf("%d",&A3);
  if(A1>=1&&A1<=13)
  	if(A2>=1&&A2<=13)
    	if(A3>=1&&A3<=13)
     		 result=A1+A2+A3;
    	 		if(result>=22)
  					printf("bust");
  				else 
   					printf("win");
 return 0;
