Given N point on a 2D plane as pair of (x, y) co-ordinates, Write a program to find maximum number of point which lie on the same line.

**Example 1**

```
Input: A[][] = [[1,1],[2,2],[1,2],[3,3],[2,3]]
Output: 3
Explanation: The maximum number of point which lie on same line are 3, those points are [1,1], [2, 2] and [3, 3]
```

**Example 2**

```
Input: A[][] = [[1,1],[3,2],[5,3],[4,1],[2,3],[1,4]]
Output: 4
Explanation: The maximum number of point which lie on same line are 4, those points are [3,2], [4,1], [2,3] and [1, 4].
