Solusi saya tidak menggunakan hashing, itu benar-benar memeriksa masing-masing piksel gambar dan memutuskan berdasarkan itu. Saya menemukan bahwa itu sudah cukup untuk memeriksa komponen biru dari modulo gambar 9. Idenya adalah untuk membagi berulang kali berdasarkan nilai pixel.B% 9, seperti:
b.GetPixel(3,4).B % 9 < 7 ? "Russian Language" : (b.GetPixel(8,4).B % 9 < 6 ? "Project Management" : "Philosophy")

Beberapa orang telah menggunakan fungsi kompresi bawaan dalam solusi mereka. Saya membuat sendiri, menulis naskah yang mengidentifikasi substring umum dan menggantinya dengan steno karakter tunggal. Kode dikompresi ke string by-by 2502 berikut:

Kamus yang diperlukan untuk dekompresi hanya 108 byte:
: & ;<%!;|ic;`,4;_#3?;^at;]er;[%$;@in;>Science;~'!;/Language;+'$;*!0,0#3?;'$:;%#7?;$\";#).B%9<;!b.GetPixel(
Kamus menggunakan titik koma sebagai pembatas, dan berisi karakter tunggal diikuti oleh dekompresi mereka. Jadi untuk mendekompres, ":" pertama-tama akan diganti dengan "&", lalu "<" oleh "%!", "|" oleh "ic", dan sebagainya. Dekompresi string c dapat diekspresikan dengan cara yang cukup ringkas:
foreach (var s in "[dictionary]".Split(';')) c = c.Replace(s[0] + "", s.Substring(1));
