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()
{
    int A1,A2,A3;
    scanf("%d%d%d",&A1,&A2,&A3);
    if(A1>=1&&A1<=13&&A2>=1&&A2<=13&&A3>=1&&A3<=13){
        if(A1+A2+A3<=21){
            printf("win");
        }else{
            printf("bust");
        }
    }
    
    return 0;
}
