Для составления 4-значных чисел используются цифры 1, 2, 3, 4, 5, при этом соблюдаются следующие правила: На первом месте стоит одна из цифр 1, 2 или 4. После каждой четной цифры идет нечетная, а после каждой нечетной - четная. Третьей цифрой не может быть цифра 3. Какое из перечисленных чисел получено по этим правилам?

ответ: как я понял, 1 тб на Fat 32 не поддерживается на всех операционках (кроме Windows NT 3.51, там кластер состовляет 32 гига)
