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 Python (3.4.3) (judge verdict: Runtime Error)

MOD = 10**9 + 7
n = int(input())
a = list(map(int,intput().split()))

cnt = [0] * 60

for num in a:
  for j in range(60):
    cnt[j] += num >> j
ans = 0
for b in range(60):
  ans += cnt[b] * (n-cnt[b]) << b
  
ans %= MOD
print(ans)
