CelebrationElection: 合格祝賀会における選出

Enter Content と思われる予備校の開催する合格祝賀会において一番大きな巨大数を構成できた参加者が勝ちのゲームで、ルールは次の通り。

main.dart

import "dart:math";

void main(){

   final int voterCount = 30;

  final int maxVote = 100;

  final int sampleCount = 7;

  for(_ in Iterable<int>generate(sampleCount, (int i) => i)){

    print(celebrationElectionSample(voterCount, maxVote));

  }

}

Iterable<int> celebrationElectionSample(int voterCount, int maxVote, [Random? r]) => celebrationElect(Iterable<int>.generate(voterCount, (_) => (r ?? Random()).nextInt(maxVote)));

Iterable<int> celebrationElect(Iterable<int> votes, {int electCount = 4, int cutbackMargin = 11}) => _celebrationElect(votes..sort(), electCount: electCount, cutbackMargin: cutbackMargin);

Iterable<int> _celebrationElect(Iterable<int> votes, {int electCount = 4, int cutbackMargin = 11}) => votes.where((int v) => v < Iterable<(int, int)>.generate(votes.length - 1, (int i) => (votes[i + 1], votes[i])).where(((int, int) e) => e.$1 - e.$2 >= cutbackMargin).map<int>(((int, int) e) => e.$1).fold<int>(votes.fold<int>(0, (int prev, int curr) => max<int>(prev, curr) + 1), (int prev, int curr) => min<int>(prev, curr))).reversed.take(electCount).reversed;
