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: Accepted)

#include <stdio.h>

// min
int main(void){
  int a1 = 0, a2 = 0, a3 = 0;
  int sum = 0;
  scanf("%d%d%d", &a1, &a2, &a3);

  sum = a1 + a2 + a3;

  if(sum >= 22){
    printf("bust\n");
  }else{
    printf("win\n");
  }

  return 0;

}
