Meine Lösung verwendet kein Hashing, sondern untersucht die einzelnen Pixel des Bildes und entscheidet darauf basierend. Ich habe festgestellt, dass es ausreicht, die blaue Komponente von image modulo 9 zu untersuchen. Die Idee ist, wiederholt anhand des Werts von pixel.B% 9 zu teilen.
b.GetPixel(3,4).B % 9 < 7 ? "Russian Language" : (b.GetPixel(8,4).B % 9 < 6 ? "Project Management" : "Philosophy")

Einige Benutzer haben in ihren Lösungen integrierte Komprimierungsfunktionen verwendet. Ich habe mein eigenes Skript erstellt, in dem häufig verwendete Teilzeichenfolgen identifiziert und durch einzelne Kurzzeichen ersetzt werden. Der Code wird in die folgende 2502 Bye-Zeichenfolge komprimiert:

Das zur Dekomprimierung benötigte Wörterbuch ist nur 108 Byte groß:
: & ;<%!;|ic;`,4;_#3?;^at;]er;[%$;@in;>Science;~'!;/Language;+'$;*!0,0#3?;'$:;%#7?;$\";#).B%9<;!b.GetPixel(
Das Wörterbuch verwendet Semikolons als Trennzeichen und enthält einzelne Zeichen, gefolgt von deren Dekomprimierung. Um zu dekomprimieren, wird ":" zuerst durch "&" und dann durch "<" durch "%!", "|" Ersetzt. von "ic" und so weiter. Die Dekomprimierung eines Strings c kann auf ganz kurze Weise ausgedrückt werden:
foreach (var s in "[dictionary]".Split(';')) c = c.Replace(s[0] + "", s.Substring(1));
Nach der Dekomprimierung benutze ich etwas Reflection Black-Magic, um den Code im laufenden Betrieb zu kompilieren und auszuführen:
