}~/.opera директория есть? Возможно там в папке cache.
Как перезапустить только один из сервисов с обновлением volumes?
docker compose up -d service.И можно в контейнерах указать не отдельные файлы, а папку всего nginx сразу?

F(n)) может вызвать максимум 2 подфункции (F(n - 1) и F(n -2)).return F(n -1) + F(n - 2). Ответ на твой вопрос кроется здесь.int prev = F(n - 1);
int prevPrev = F(n - 2);
return prev + prevPrev;return F(n - 1) + F(n - 2)1 + 1
