You have N stacks of books. Each stack of books has some non zero height Hi equal to the number of books on that stack ( considering all the books are identical and each book has a height of 1 unit ). In one move, you can select any number of consecutive stacks of books such that the height of each selected stack of books Hi <= K . Once such a sequence of stacks is chosen , You can collect any number of books from the chosen sequence of stacks .

What is the maximum number of books that you can collect this way ?

**Input:**

The first line of input contains an integer T denoting the no of test cases . Then T test cases follow. First line of each test case contains two space separated integers N and K where N is the number of stacks of books. Second line of each test case contains N space separated integers denoting the number of books Hi on each stack.

**Output:**

For each test case, print the maximum number of books you can collect.

**Constraints:**

1<=T<=105

1<=N<=105

1<=K<=109

1<=Hi<=109

**Example(To be used only for expected output):**

**Input**

2

8 1

3 2 2 3 1 1 1 3

8 2

3 2 2 3 1 1 1 3

**Output**

3

4

**Explanation :**

**For the first test case**

N = 8 , K = 1 { 3 2 2 3 1 1 1 3 }

We can collect maximum books from consecutive stacks numbered 5, 6 and 7 having height less than equal to K.

**For the second test case**

N = 8 , K = 2 { 3 2 2 3 1 1 1 3 }

We can collect maximum books from consecutive stacks numbered 2 and 3 having height less than equal to K.
