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 (3.8.2) (judge verdict: Runtime Error)

n = int(input())
a = [[] for _ in range(n)]
for i in range(n):
  num = int(input())
  for j in range(num):
    person, state = map(int, input().split())
    a[i].append([person-1, state])
honest = 0
for i in range(1, 2**n):
  flag = True
  for j in range(n):
    if (i>>j)&1 == 1:
      for x, y in a[j]:
        if (i>>x)&1 != y:
          flag = False
          break
  if flag:
    honest = max(honest, bin(i)[2:].count('1'))
print(honest)
