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<bits/stdc++.h>
#include<iostream>
using namespace std;

typedef long long ll;
const int N = 2000006;



int main(){
	ios_base::sync_with_stdio(0); cin.tie(0); cout.tie(0);
	
	int a,b,c;
	cin>>a>>b>>c;
	if(a + b + c >= 22){
		cout<<"bust";
	}else{
		cout<<"win";
	}
	
	return 0;
}
