A10743. Vladik and fractions

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.

The single line contains single integer $n$ ( $1<=n<=10^{4}$ ).

If the answer exists, print $3$ distinct numbers $x$ , $y$ and $z$ ( $1<=x,y,z<=10^{9}$ , $x≠y$ , $x≠z$ , $y≠z$ ). Otherwise print -1.

If there are multiple answers, print any of them.

对于$100$%的数据满足$n \leq 10^4$
要求答案中$x,y,z \leq 2* 10^{9}$
