Given an array A. Let X be an element in the array which has the maximum frequency. The task is to find the smallest sub segment of the array which also has X as the maximum frequency element.

**Note:** if two or more elements have the same frequency (i.e., maximum frequency) and the same sub segment size then print the sub segment** **which occurs first in the array.

**Input:**

The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. First line of each test case contains an Integer N denoting size of array and the second line contains N space separated elements.

**Output:**

For each test case, print the required sub segment of array in new line.

**Constraints:**

1<=T<=100

1<=N<=10^{5}

1<=A[i]<=10^{5}

**Example:
Input:**

3

8

4 1 1 2 2 1 3 3

5

1 2 2 3 1

6

1 4 3 3 5 5

1 1 2 2 1

2 2

3 3

**Explanation:**

```
Input : A[] = {1, 2, 2, 3, 1}
Output : 2, 2
Note that there are two elements that appear
two times, 1 and 2. The smallest window for
1 is whole array and smallest window for 2 is
{2, 2}. Since window for 2 is smaller, this is
our output.
```
