Alice are given an array A[1..N] with N numbers.
Now Alice want to build an array B by a parameter K as following rules:
Initially, the array B is empty. Consider each interval in array A. If the length of this interval is less than K, then ignore this interval. Otherwise, find the K-th largest number in this interval and add this number into array B.
In fact Alice doesn't care each element in the array B. She only wants to know the M-th largest element in the array B. Please help her to find this number.
The first line is the number of test cases.
For each test case, the first line contains three positive numbers N(1≤N≤105),K(1≤K≤N),M. The second line contains N numbers Ai(1≤Ai≤109).
It's guaranteed that M is not greater than the length of the array B.
For each test case, output a single line containing the M-th largest element in the array B.
