Q. |
## The most important condition for which closest pair is calculated for the points (pi, pj) is? |

A. | i>j |

B. | i!=j |

C. | i=j |

D. | i<j |

Answer» D. i<j | |

Explanation: to avoid computing the distance between the same pair of points twice, we consider only the pair of points (pi, pj) for which i<j. |
