There is an array \(a[ 1... n ]\), which has \(n\) integers.

Consider all the consecutive intervals of \(a[ ]\) which have at least \(K\) integers. We find the \(K\)-th largest element from each of such intervals, and add these elements into an array \(B\) which is initially empty. Notice that the same element can be added for multiple times. Obviously, finally the length of \(B\) is \(\frac{(n+2-K)(n+1-K)}{2}\).

For example, \(a=[4,5,5,8,6]\) and \(K=4\). Then the consecutive intervals with at least \(K=4\) integers are \([4,5,5,8], [5,5,8,6], [4,5,5,8,6]\). After finding the \(K\)-th largest elements, we get \(B=[4,5,5]\).

Do you know what is the \(M\)-th largest integer in array \(B[ ]\)?


The first line contains an integer \(T(1\leq T\leq 5)\), indicating the number of test cases.

For each test case, the first line contains three integers \(n(1\leq n\leq 10^5), K(1\leq K\leq n), M(1\leq M\leq \frac{(n+2-K)(n+1-K)}{2} )\). The second line contains \(n\) integers \(a[i] (1\leq a[i]\leq 10^9)\).


For each test case, output the answer in one line.
