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: Wrong Answer)

flag=0
while flag==0:
    a,b,c = input('Enter 3 number:').split()
    a = int(a)
    b = int(b)
    c  = int(c)

    if 1<=a<=13 and 1<=b<=13 and 1<=c<=13:
        flag=1

score = a+b+c
if score>=22:
    print("bust")
else:
    print("win")
