Обозначим через mod(a, b) остаток от деления натурального числа a на натуральное число b. Алгоритм вычисления значения функции F(n), где n  — целое неотрицательное число, задан следующими соотношениями: F(0) = 0; F(n) = F(n / 3), если n > 0 и при этом mod(n, 3)  =  0; F(n) = mod(n, 3) + F(n − mod(n, 3)), если mod(n, 3) > 0. Назовите минимальное значение n, для которого F(n) = 11.
