B'Two best friends Serozha and Gena play a game. Initially there is one pile consisting of n stones on the table. During one move one pile should be taken and divided into an arbitrary number of piles consisting of a1 xe2 x80 x89> xe2 x80 x89a2 xe2 x80 x89> xe2 x80 x89... xe2 x80 x89> xe2 x80 x89ak xe2 x80 x89> xe2 x80 x890 stones. The piles should meet the condition a1 xe2 x80 x89- xe2 x80 x89a2 xe2 x80 x89= xe2 x80 x89a2 xe2 x80 x89- xe2 x80 x89a3 xe2 x80 x89= xe2 x80 x89... xe2 x80 x89= xe2 x80 x89ak xe2 x80 x89- xe2 x80 x891 xe2 x80 x89- xe2 x80 x89ak xe2 x80 x89= xe2 x80 x891. Naturally, the number of piles k should be no less than two. The friends play in turns. The player who cannot make a move loses. Serozha makes the first move. Who will win if both players play in the optimal way? The single line contains a single integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105). If Serozha wins, print k, which represents the minimal number of piles into which he can split the initial one during the first move in order to win the game. If Gena wins, print "-1" (without the quotes).'...
