Вдогонку числа:
Исходный размер=23,193,521 байт
Архив1 (в маленьком файле 555)=2,918,177 байт
Архив2 (в маленьком файле 111)=2,918,148 байт
Из самописной программы:
Несовпадений=2,904,775
Архив1=2,918,177
Архив2=2,918,148
Минимум=2,918,148
Дельта=29
Разница=99,54%
Формула:
Разница=(Несовпадений+Дельта)*100/(Минимум+Дельта)
Программа для сравнения приложена.
