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 (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int main(){
    int n1,n2,n3,sum=0;
    scanf("%d%d%d",&n1,&n2,&n3);
    sum=n1+n2+n3;
    if(0<n1 && n1<14 && 0<n2 && n2<14 && 0<n3 && n3<14){
        if(sum>=22){
        printf("bust");
        }
        else{
        printf("win");
        }
    }
    return 0;
}
