Giải pháp của tôi không sử dụng băm, nó thực sự kiểm tra từng pixel của hình ảnh và quyết định dựa trên đó. Tôi phát hiện ra rằng nó đủ để kiểm tra thành phần màu xanh của modulo hình ảnh 9. Ý tưởng là phân tách nhiều lần dựa trên giá trị của pixel.B% 9, như vậy:
b.GetPixel(3,4).B % 9 < 7 ? "Russian Language" : (b.GetPixel(8,4).B % 9 < 6 ? "Project Management" : "Philosophy")
Sử dụng một tập lệnh, tôi đã tạo ra chương trình quái dị sau (5197 byte) để giải quyết vấn đề bằng cách sử dụng cây quyết định nhị phân:

Một số người đã sử dụng các hàm nén tích hợp trong các giải pháp của họ. Tôi tự làm, viết một kịch bản xác định các chuỗi con chung và thay thế chúng bằng các tốc ký đơn ký tự. Mã được nén theo chuỗi 2502 sau đây:

Từ điển cần thiết cho giải nén chỉ là 108 byte:
: & ;<%!;|ic;`,4;_#3?;^at;]er;[%$;@in;>Science;~'!;/Language;+'$;*!0,0#3?;'$:;%#7?;$\";#).B%9<;!b.GetPixel(
Từ điển sử dụng dấu chấm phẩy làm dấu phân cách và chứa các ký tự đơn theo sau là giải nén của chúng. Vì vậy, để giải nén, ":" trước tiên sẽ được thay thế bằng "&", sau đó "<" bằng "%!", "|" bởi "ic", v.v. Giải nén chuỗi c có thể được thể hiện theo cách khá súc tích:
foreach (var s in "[dictionary]".Split(';')) c = c.Replace(s[0] + "", s.Substring(1));
