Problem Description
Give an array A, the index starts from 1.
Now we want to know Bi=maxi∤jAj , i≥2.
Now we want to know Bi=maxi∤jAj , i≥2.
Input
The first line of the input gives the number of test cases T; T test cases follow.
Each case begins with one line with one integer n : the size of array A.
Next one line contains n integers, separated by space, ith number is Ai.
Limits
T≤20
2≤n≤100000
1≤Ai≤1000000000
∑n≤700000
