Given an integer sequence {A1,a2...,an}, find the continuous non-empty string {ax,ax+1,..., ay}, making the subsequence and the largest, wherein, 1<=x<=y<=n.

Input

The first line is an integer N (n<=10) that represents the number of groups of test data)
The first line of each set of test data is an integer n indicating that the sequence has n integers, followed by n integers I ( -100=<i<=100), representing all the elements in the series. (0<n<=1000000)

Output

For each set of test data output and the maximum contiguous substring of the and.
