题目描述
The GCD table G of size n×n for an array of positive integers a of length n is defined by formula
Let us remind you that the greatest common divisor (GCD) of two positive integers x and y is the greatest integer that is divisor of both x and y , it is denoted as
. For example, for array a=4,3,6,2 of length 4 the GCD table will look as follows:
Given all the numbers of the GCD table G , restore array a .
输入格式
The first line contains number n ( 1<=n<=500 ) — the length of array a . The second line contains n2 space-separated numbers — the elements of the GCD table of G for array a .
All the numbers in the table are positive integers, not exceeding 109 . Note that the elements are given in an arbitrary order. It is guaranteed that the set of the input data corresponds to some array a .
输出格式
In the single line print n positive integers — the elements of array a . If there are multiple possible solutions, you are allowed to print any of them.
