Prompt Title: C# Remove Duplicate Rows

Certainly! Here's a C# code snippet that reads the data, compares each row with the next row while ignoring the 4th column, and removes any duplicate rows:

using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        List<int[]> data = new List<int[]>
        {
            new int[] { 1, 0, 1, 0, 0, 0 },
            new int[] { 1, 0, 1, 0, 0, 1 },
            new int[] { 1, 0, 1, 0, 0, 2 },
            new int[] { 1, 0, 1, 0, 1, 0 },
            new int[] { 1, 0, 1, 0, 1, 1 },
            new int[] { 1, 0, 1, 0, 1, 2 },
            new int[] { 1, 0, 1, 0, 2, 0 },
            new int[] { 1, 0, 1, 0, 2, 1 },
            new int[] { 1, 0, 1, 0, 2, 2 },
            new int[] { 1, 0, 1, 1, 0, 0 },
            new int[] { 1, 0, 1, 1, 0, 1 },
            new int[] { 1, 0, 1, 1, 0, 2 },
            new int[] { 1, 0, 1, 1, 1, 0 },
            new int[] { 1, 0, 1, 1, 1, 1 },
            new int[] { 1, 0, 1, 1, 1, 2 },
            new int[] { 1, 0, 1, 1, 2, 0 },
            new int[] { 1, 0, 1, 1, 2, 1 },
            new int[] { 1, 0, 1, 1, 2, 2 },
            new int[] { 1, 0, 1, 2, 0, 0 }
            // Add the rest of the data here...
        };

        List<int[]> result = RemoveDuplicateRows(data);

        foreach (var row in result)
        {
            Console.WriteLine(string.Join(" ", row));
        }
    }

    static List<int[]> RemoveDuplicateRows(List<int[]> data)
    {
        List<int[]> result = new List<int[]>();

        for (int i = 0; i < data.Count - 1; i++)
        {
            bool isDuplicate = false;

            for (int j = i + 1; j < data.Count; j++)
            {
                if (Enumerable.SequenceEqual(data[i].Take(3).Concat(data[i].Skip(4)), data[j].Take(3).Concat(data[j].Skip(4))))
                {
                    isDuplicate = true;
                    break;
                }
            }

            if (!isDuplicate)
            {
                result.Add(data[i]);
            }
        }

        // Adding the last row, assuming it's not a duplicate of the previous ones
        result.Add(data.Last());

        return result;
    }
}

In this code, the RemoveDuplicateRows method compares each row (excluding the 4th column) with the subsequent rows. If a duplicate row is found, it's not added to the result list. The last row is then added to the result list as well since it's assumed to not be a duplicate of the previous ones.
