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 <= 10^{4}

3. 1 <= M <= N - K + 1

4. 1 <= arr[i] <= 10^{5}

**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
