  • Given 3 points, output one that is separated from its nearest neighbour by the largest distance.
  • ## Input
  • - 3 distinct points (that is, no 2 points are in the same position).
  • - Each point is a pair of positive integers.
  • ## Output
  • - A single point, as a pair of positive integers.
  • - The distance between this point and its nearest neighbour must be greater than or equal to the distance from either of the other points to their nearest neighbour.
  • - If all 3 of the input points have this property[^1], you may output any of them, but you must output only 1 of them.
  • ## Examples
  • ### Example with a single valid output
  • Input points and distance to nearest neighbour:
  • ```text
  • 1,3 : 1.4142135
  • 2,2 : 1.0000000
  • 3,2 : 1.0000000
  • ```
  • Output:
  • ```text
  • 1,3
  • ```
  • ### Example with three valid outputs
  • Input points and distance to nearest neighbour:
  • ```text
  • 6,5 : 3.6055512
  • 4,2 : 3.6055512
  • 9,3 : 3.6055512
  • ```
  • All the nearest neighbour distances are the same, so any 1 of the following is a valid output:
  • ```text
  • 6,5
  • 4,2
  • 9,3
  • ```
  • ## Test cases
  • Note that if there is more than 1 valid output, you must output only 1 of them.
  • - Test case are in the format `inputs : outputs`.
  • - Inputs are in the format `point1 ; point2 ; point3`.
  • - Outputs are in the format `point1 | point2 | point3`.
  • - Points are in the format `x,y`.

Most isolated of 3 points
Given 3 points, output one that is separated from its nearest neighbour by the largest distance.

## Input
- 3 distinct points (that is, no 2 points are in the same position).
- Each point is a pair of positive integers.

## Output
- A single point, as a pair of positive integers.
- The distance between this point and its nearest neighbour must be greater than or equal to the distance from either of the other points to their nearest neighbour.
- If all 3 of the input points have this property[^1], you may output any of them, but you must output only 1 of them.

## Examples
### Example with a single valid output
Input points and distance to nearest neighbour:

```text
1,3 : 1.4142135
2,2 : 1.0000000
3,2 : 1.0000000
```

Output:

```text
1,3
```

### Example with three valid outputs
Input points and distance to nearest neighbour:

```text
6,5 : 3.6055512
4,2 : 3.6055512
9,3 : 3.6055512
```

All the nearest neighbour distances are the same, so any 1 of the following is a valid output:

```text
6,5
4,2
9,3
```

## Test cases
Note that if there is more than 1 valid output, you must output only 1 of them.
- Test case are in the format `inputs : outputs`.
- Inputs are in the format `point1 ; point2 ; point3`.
- Outputs are in the format `point1 | point2 | point3`.
- Points are in the format `x,y`.
