Given an array of distinct elements. Your task is to find the third largest element in it. You have to complete the function** thirdLargest** which takes two argument. The first argument is the array **a[]** and the second argument is the **size of the array (n)**. The function returns an integer denoting the third largest element in the array a[]. The function should return **-1** if there are less than 3 elements in input.

**Input:**

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 array. The second line of each test case contains N space separated values of the array a[].

**Output:**

Output for each test case will be the third largest element of the array .

**Constraints:**

1 ≤ T ≤ 100

1 ≤ N ≤ 10^{3}

1 ≤ A[i] ≤ 10^{3}

**Example(To be used for only expected output):**

**Input:**

1

5

2 4 1 3 5

**Output:**
