Given an array of distinct elements. Find the third largest element in it. 

The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. The first line of each test case is N, size of the array. The second line of each test case contains N space separated values of the array a[].

Print the third largest element of the array. If the array has less than 3 elements print -1. 

Your Task:
Complete the function thirdLargest() which takes the array a[] and the size of the array, n, as input parameters and returns the third largest element in the array. It return -1 if there are less than 3 elements in the given array.

Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)

1 ≤ T ≤ 100
1 ≤ N ≤ 105
1 ≤ A[i] ≤ 105

Sample Input:
2 4 1 3 5
10 2

Sample Output:

Test Case 1: Largest number is 5, followed by 4 and then 3. Hence, the answer is 3.
Test Case 2: Since there are less than 3 numbers, output is -1.
