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

You don’t need to print anything; it has been handled. Implement the provided function to solve the problem.

Accepted Answer

Find the third largest element in an array of distinct integers.

Sort the array in descending order and return the element at index 2.
Handle cases where the array has less than 3 elements separately.
Consider edge cases like negative integers and duplicates.
