Problem Description

New Year is Coming! 
ailyanlu is very happy today! and he is playing a chessboard game with 8600. 
The size of the chessboard is n*n. A stone is placed in a corner square. They play alternatively with 8600 having the first move. Each time, player is allowed to move the stone to an unvisited neighbor square horizontally or vertically. The one who can't make a move will lose the game. If both play perfectly, who will win the game?

 

Input

The input is a sequence of positive integers each in a separate line. 
The integers are between 1 and 10000, inclusive,(means 1 <= n <= 10000) indicating the size of the chessboard. The end of the input is indicated by a zero.

 

Output

Output the winner ("8600" or "ailyanlu") for each input line except the last zero. 
No other characters should be inserted in the output.

 

Sample Input

2
0

 

Sample Output

8600

 

题意：给定一个n*n的表格，在一个角上放入一块石头，然后两个人轮流移动石头，仅仅能水平和竖直移动石子。并且不能移到已经訪问的格子。最后没法移动的玩家为输者。如今输入随意的n输出谁输谁胜。

这个随便画两个就能非常easy的推算出胜负。
