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.

#include <stdio.h>

int main(void)
{
    int a;
    int b;
    int c;
    int ans;
    
    scanf("%d %d %d",a,b,c);
    
    ans = a + b + c;
    
    if(ans>=22){
        printf("bust");
    }
    else{
        printf("win");
    }
    
    return 0;
