Score : 100 points

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 Python (3.4.3) (judge verdict: Runtime Error)

#include <iostream>
#define REP(i, a, b) for (auto i = (a); i < (b); ++i)
using namespace std;

using ll = long long;

signed main() {
	ios_base::sync_with_stdio(false);
	cin.tie(nullptr);

	int x, y, z; cin >> x >> y >> z;
	cout << (x + y + z < 22 ? "win" : "bust");
}
