Given a matrix of m*n size, the task is to count all the rows in a matrix that are sorted either in strictly increasing order or in strictly decreasing order?

Examples:

```
Input : m = 4, n = 5
mat[m][n] = 1 2 3 4 5
4 3 1 2 6
8 7 6 5 4
5 7 8 9 10
Output: 3
```

**Input:**

The first line of input contains a single integer T denoting the number of test cases. Then** **T test cases follow. Each test case consists of two lines.

First line of each test case consist of two space separated integers M and N, denoting the number of element in a row and column respectively.

Second line of each test case consists of N*M space separated integers denoting the elements in the matrix in row major order.

**Output:**

Corresponding to each test case, print in a new line, count of sorted rows.

**Constraints:**

1<=T<=200

1<=N,M<=100

**Example:**

**Input:**

2

3 3

3 40 38 44 52 54 57 60 69

3 2

18 40 27 38 55 67

**Output:**
