Question Number: #Com4799

Suppose, the seed of any positive integer n is de¡ned as follows:
                                seed(n) = n, if n < 10
                                             = seed(s(n)), otherwise,

where s(n) indicates the sum of digits of n. For example,
seed(7) = 7, seed(248) = seed(2 + 4 + 8) = seed(14) = seed(1 + 4) = seed(5) = 5 etc.

How many positive integers n, such that n < 500, will have seed (n) = 9?
