Problem Statement

#### Formally, find the largest number with minimum frequency from the given 'ARR'.

##### Example:
``````You have given an array {2, 2, 5, 50, 1} so in this array ‘50’ is the largest number with minimum frequency.
``````
##### Input Format:
``````The first line contains an integer 'T', which denotes the number of test cases or queries to be run. Then, the 'T' test cases follow.

The first line of each test case contains a positive integer 'N' denoting the size of the array.

The second line of each test case contains an array ‘ARR[i]’ containing ‘N’ number of values.
``````
##### Output Format:
``````For each test case, print the largest number with minimum frequency.
``````
##### Note:
``````You do not need to print anything. It has already been taken care of. Just implement the given function.
``````

#### Constraints:

``````1 <= T <= 10^2
1 <= N <= 10^3
1 <= ARR[i] <= 10^9

Where ‘T’ represents the number of test cases and ‘N’ represents the size of array and ‘ARR[i]’ represents the elements of array.

#### Sample Input 1:

``````2
5
9 9 9 2 5
5
5 5 4 6 4
``````

#### Sample Output 1:

``````5
6
``````

#### Explanation For Sample Input 1:

``````In first test case, ‘5’ is the size of the array. In the second line elements of the array are given so according to this array ‘5’ and ‘2’ are the elements with minimum frequency but as ‘5 is larger than ‘2’, So, ‘5’ is the answer.

In the second test case, ‘6’ is the number with the smallest frequency.
``````

#### Sample Input 2 :

``````2
3
1 1 1
5
50 50 1 30 30
``````

#### Sample Output 2 :

``````1
1
``````

#### Explanation For Sample Input 2:

``````In the first test case, ‘3’ is the size of the array and all elements are '1'. So, ‘1’ is the answer.

In the second test case, ‘1’ is the number with the smallest frequency.
