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 Lua (5.3.2) (judge verdict: Accepted)

local A,B,C = string.match(io.read(), "(%d+) (%d+) (%d+)");
A=tonumber(A)
B=tonumber(B)
C=tonumber(C)

if A+B+C>= 22 then print("bust")
else print("win")
end
