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>
int main()
{
  int a[3];
  int i,sum=0;
  for(i=0;i<3;i++)
  {
    scanf("%d",&a[i]);
  }
  for(i=0;i<2;i++)
  {
      if(a[i]<=13&&a[i]>=1)
    sum=sum+a[i];
    else
        exit(0);
  }
  if(sum<22)
  {
      printf("win");
  }
  else
    {
        printf("bust");
    }
}
