Problem:
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 C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<stdlib.h>
#include <string.h>

int main() {
	char s[101];
	scanf("%s", s);

	int len = strlen(s);

	int count = 0;

	if (len % 2 == 0) {
		for (int i = 0; i < len / 2; i++) {
			if (s[i] != s[len - 1 - i]) {
				count++;
			}
		}
	}
	else {
		for (int i = 0; i < (len - 1) / 2; i++) {
			if (s[i] != s[len - 1 - i]) {
				count++;
			}
		}
	}
	printf("%d", count);
	return 0;
