Most isolated of 3 points

+1
−0

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:

1,3 : 1.4142135
2,2 : 1.0000000
3,2 : 1.0000000

Output:

1,3

Example with three valid outputs

Input points and distance to nearest neighbour:

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:

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 cases 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.

Scoring

This is a code golf challenge. Your score is the number of bytes in your code. Lowest score for each language wins.

Explanations are optional, but I'm more likely to upvote answers that have one.


  1. It is not possible for exactly 2 of the input points to have this property. There will either be exactly 1 or exactly 3. ↩︎
