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 PyPy3 (7.3.0) (judge verdict: Wrong Answer)

import sys
stdin=sys.stdin

ip=lambda: int(sp())

lp=lambda:list(map(int,stdin.readline().split()))
sp=lambda:stdin.readline().rstrip()

a,b,c=lp()
if a+b+c>=22:
  print('burst')
  
else:
  print('win')
