Difficulty: Moderate

## PROBLEM STATEMENT

#### You are given an array consisting of 'N' distinct positive integers and a number 'K'. Your task is to find the kth largest element in the array.

##### Example:
``````Consider the array {2,1,5,6,3,8} and 'K' = 3, the sorted array will be {8, 6, 5, 3, 2, 1}, and the 3rd largest element will be 5.
``````
##### Note:
``````1) Kth largest element in an array is the kth element of the array when sorted in non-increasing order.

2) All the elements of the array are pairwise distinct.
``````
##### Input Format:
``````The first line of the input contains an integer 'T' denoting the number of test cases.

The first line of each test case contains two space- separated integers 'N' and 'K', as described in the problem statement.

The second line of each test case contains 'N' space-separated integers, representing the elements of the array.
``````
##### Output Format:
``````For each test case, print a single integer denoting the kth largest number in the given array.
``````
##### Note:
``````You do not need to print anything, it has already been taken care of. Just implement the given function.
``````
##### Constraints:
``````1 <= T <= 100
1 <= N <= 10^4
1 <= ARR[i] <= 10^9
1 <= K <= N

Time Limit: 1 sec
