Arrays - Exercise - 09. Kamino Factory - 90/100 в Judge

Здравейте, колеги!
Забих на една задача, която решавам вече доста часове.
Става въпрос за задачата 09. Kamino Factory(use the force!) от Arrays - Exercise.

Условие:
https://softuni.bg/trainings/resources/officedocument/67743/arrays-exercise-programming-fundamentals-with-csharp-january-2022/3606

В Judge получавам резултат 90/100, многократно преглеждам кода и не мога да въдя къде би било възможно да гръмне.
Това ми е кодът - https://pastebin.com/KQfGif0R

Всякаква градивна критика е добре дошла! :)

If validations can be compacted and simplified, especially the last if-validation outside of the for-loop. Keep also in mind that inside of your for-loop the current value as well as the next one need to be checked if equal to 1.

Standard solution code:

using System;
using System.Linq;

namespace kaminoFactory
{
	class Program
	{
		static void Main(string[] args)
		{
			int n = int.Parse(Console.ReadLine());
			string command = Console.ReadLine();
			int maxOnes = int.MinValue;
			int maxSequence = int.MinValue;
			int sequenceCounter = 0;
			int minStarter = int.MaxValue;
			int bestSequence = 0;
			string strongestSequence = string.Empty;

			while (command != "Clone them!")
			{
				sequenceCounter++;
				int[] sequence = command.Split('!', StringSplitOptions.RemoveEmptyEntries).Select(int.Parse).ToArray();
				int counterOnes = 0;
				int counterSequence = 0;
				int sequenceStarter = 0;

				for (int i = 0; i < n - 1; i++)
				{
					if (sequence[i] == 1 && sequence[i + 1] == 1)
					{
						if (counterSequence == 0)
						{
							sequenceStarter = i;
						}
						counterSequence++;
					}
				}

                foreach (int one in sequence)
                {
                    if (one == 1)
                    {
                        counterOnes++;
                    }
                }
				
				if (counterSequence > maxSequence || (sequenceStarter < minStarter && counterSequence >= maxSequence) || (sequenceStarter == minStarter && counterSequence >= maxSequence && counterOnes > maxOnes))
				{
					maxOnes = counterOnes;
					maxSequence = counterSequence;
					minStarter = sequenceStarter;
					bestSequence = sequenceCounter;
					strongestSequence = string.Join(" ", sequence);
				}
				
				command = Console.ReadLine();
			}

			Console.WriteLine($"Best DNA sample {bestSequence} with sum: {maxOnes}.");
			Console.WriteLine($"{strongestSequence}");
		}
	}
}

Кратка вметка към горното решение на Axiomatik, добре би било да се нулира броячът counterSequence между отделните инпути, защото иначе не покрива случаи като този:

9

1!1!0!1!1!0!1!1!0

1!1!1!0!0!0!0!0!0

Предлагам и сходно авторско решение:

int sampleLength = int.Parse(Console.ReadLine());
string input = "";
int sampleCounter = 0;
int[] bestSampleArray = new int[sampleLength];
int bestSequenceSum = 0;
int bestSampleNumber = 0;
int bestStartingIndex = 0;
int bestSequence = int.MinValue;
while ((input = Console.ReadLine()) != "Clone them!")
{
    sampleCounter++;
    int[] sequenceArray = input.Split('!', StringSplitOptions.RemoveEmptyEntries).Select(int.Parse).ToArray();
    int sequenceCounter = 0;
    int currentBestSequenceCounter = 0;
    int sequenceStart = 0;
    int currentBestStartingIndex = 0;
    int currentSum = 0;
    for (int i = 0; i < sequenceArray.Length; i++)
    {
        if (sequenceArray[i] == 1)
        {
            if (sequenceCounter == 0)
            {
                sequenceStart = i;
            }
            currentSum++;
            sequenceCounter++;
        }
        if (sequenceArray[i] == 0 || i == sequenceArray.Length - 1)
        {
            if (currentBestSequenceCounter < sequenceCounter)
            {
                currentBestStartingIndex = sequenceStart;
                currentBestSequenceCounter = sequenceCounter;
            }
            sequenceCounter = 0;
        }
    }
    if (currentBestSequenceCounter > bestSequence
        || (currentBestSequenceCounter == bestSequence && currentBestStartingIndex < bestStartingIndex)
        || (currentBestSequenceCounter == bestSequence && currentBestStartingIndex == bestStartingIndex && currentSum > bestSequenceSum)
       )
    {
        bestSequence = currentBestSequenceCounter;
        bestSampleNumber = sampleCounter;
        bestSequenceSum = currentSum;
        bestStartingIndex = currentBestStartingIndex; ;
        bestSampleArray = sequenceArray;
    }
}
Console.WriteLine($"Best DNA sample {bestSampleNumber} with sum: {bestSequenceSum}.");
Console.WriteLine(string.Join(" ", bestSampleArray));
