Vladik and Chloe decided to determine who of them is better at math. Vladik claimed that for any positive integer $ n $ he can represent fraction  as a sum of three distinct positive fractions in form . Help Vladik with that, i.e for a given $ n $ find three distinct positive integers $ x $ , $ y $ and $ z $ such that . Because Chloe can't check Vladik's answer if the numbers are large, he asks you to print numbers not exceeding $ 10^{9} $ . If there is no such answer, print -1.
