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>
main()
{
    int A1,A2,A3,s=0;
    scanf("%A1 %A2 %A3",&A1,&A2,&A3);
    s=A1+A2+A3;
    if(s>=22)
    {
        printf('bust');

    }
    else
        printf('win');
}
