Given an array arr[] and a number k. The task is to delete k elements which are smaller than next element (i.e., we delete arr[i] if arr[i] < arr[i+1]) or become smaller than next because next element is deleted.

**Input:**

The first line contains an integer **T, **the number of test cases. For each test case, the first line contains an integer **n, **denoting the size of the array. Next line contains n space separated integers, followed by an integer **k**, denoting the number of elements to be deleted from the array.

**Output:**

For each test case, the output is the array arr[] after deleting the k elements from the array if possible, else print the left array as it is.

**Constraints:**

1<=T<=100

2<=n<=100

1<=k<=100

**Example:**
