Find the Third Greatest Element

Given an array 'ARR' of 'N' distinct integers, determine the third largest element in the array.

Input:

The first line contains a single integer 'T' representing the number of test cases. Each test case consists of: A single integer 'N', the number of elements in the array, on a new line. Followed by 'N' space-separated distinct integers that comprise the array 'ARR'.

Output:

For each test case, output the third largest element from the array 'ARR'.

Example:

Input:
T = 2
N = 5
ARR = [7, 4, 9, 1, 3]
N = 4
ARR = [10, 20, 30, 40]

Output:
4
20

Constraints:

1
