Задача: создать игру Пазл;
Использованный API: GTK/GDK;
Среда разработки: Visual Studio 2008;
Игра пазл:
Имеется два окна: пример картинки и сам пазл. Нужно, переставляя части пазла на пустое место, собрать картинку.
Основная задача - убедиться, что пазл соберется. Для этого необходимо проверить на четность количество инверсий в перестановках. Если оно четное - пазл соберется верно, иначе мы перемешиваем части пазла еще раз.
