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 9.2.1) (judge verdict: Accepted)

#include<iostream>
using namespace std;
int main()
{
    int a1,a2,a3,a;

    cin>>a1>>a2>>a3;

    if(a1>0&&a1<14&&a2>0&&a2<14&&a3>0&&a3<14)
    {
        a=a1+a2+a3;
        if(a<22)
            cout<<"win"<<endl;
        else
            cout<<"bust"<<endl;
    }

    return 0;
}
