The
favorite resting place of the Ural programmers is Threenland island.
There is only one tribulation: dollars and euro don’t go about here. So
the tourists are to exchange their money into threets (the currency of
Threenland). There go about 1 threet, 3 threets, 9 threets, 27 threets,
…, 3k threets, … Once programmer Vasechkin, after the N-threets
bill was given to him found out, that he’d got one paper of each
denomination. Waiters in Threenland have a custom to keep the change.
Waiters like to get the tip that can be presented by a set of papers in
which paper of each denomination appears not more than once. Otherwise
their feelings are hurt. They have a peeve on a client if they don’t get
tips at all. Help please Vasechkin to pay for the dinner and not to
hurt the waiter.
Input
consists of an integer N. 1 ≤ N ≤ 107.
Output
Output
two integers separated with a space – that is the sum that Vasechkin is
to pay and an amount of tips. If there are several solutions choose any
of them. If there is no solution output 0. Remember that Ural
programmers are not rich, so Vasechkin can’t pay more than 4294967291
threets.
