Given an array of N values. Print the number which has maximum number of zeroes. If there are no zeroes then print -1.

Note: If there are multiple numbers with same (max) number of zeroes then print the Maximum number among them.

Input:
The first line of input contains an integer T denoting the number of test cases. T testcases follow. Each testcase contains two lines of input. The first line consists of an integer N. The next line consists of N spaced integers.

Output:
For each testcase, print the number with maximum number of zeroes.

Constraints: 
1<=T<=100
1<=N<=107
1<=A[i]<=10100

Example:
Input:

1
5
10 20 3000 9999 200
Output:
3000

Explanation:
Testcase1:
3000 hsa maximum number of zeroes so we print it.
