Given `N` positive integers, divide them in two disjoint non-empty groups in such a way that the greatest common divisor of each group is greater than 1.
Input file format
Input file contains integer `N`, followed by `N` integers `a_1\ a_2…\ a_N`.
Output file format
Output file must contain numbers belonging to the first group, followed by 0 and then by numbers belonging to the second group. If there is no solution, output a single number `-1`. If there is more than one solution, output any of them.
Constraints
`2\ ≤\ N\ ≤\ 1000`, `2\ ≤\ a_i\ ≤\ 10^8`
