Given an integer array arr of size N and two integers K and M, the task is to find M largest sums of K sized subarrays. 

Input:
1. The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.
2. The first line of each test case contains three integers N, K, and M.
3. The next line contains N space-separated integers.

Output: For each test case, print M space-separated integers (Print the sums from the maximum to minimum)

Constraints:
1. 1 <= T <= 100
2. 1 <= K <= N <= 10⁴
3. 1 <= M <= N - K + 1
4. 1 <= arr[i] <= 10⁵

Example:
Input:
2
5 2 3
10 11 10 11 12
5 5 1
1 2 3 4 5
 

Output:
23 21 21
15

Explanation:
Test Case 1: 2 sized subarray sum are {21, 21, 21, 21, 23}, We need to print 3 largest sums from maximum to minimum
