Description
A tennis tournament with n participants is running. The participants are playing by an olympic system, so the winners move on and the losers drop out.
The tournament takes place in the following way (below, m is the number of the participants of the current round):
- let k be the maximal power of the number 2 such that k ≤ m,
- k participants compete in the current round and a half of them passes to the next round, the other m - k participants pass to the next round directly,
- when only one participant remains, the tournament finishes.
Each match requires b bottles of water for each participant and one bottle for the judge. Besides p towels are given to each participant for the whole tournament.
Find the number of bottles and towels needed for the tournament.
Note that it's a tennis tournament so in each match two participants compete (one of them will win and the other will lose).
Input
The only line contains three integers n, b, p (1 ≤ n, b, p ≤ 500) — the number of participants and the parameters described in the problem statement.
Output
Print two integers x and y — the number of bottles and towels need for the tournament.
Sample Input
Input
5 2 3
Output
20 15
Input
8 2 4
Output
35 32
Hint
In the first example will be three rounds:
- in the first round will be two matches and for each match 5 bottles of water are needed (two for each of the participants and one for the judge),
- in the second round will be only one match, so we need another 5 bottles of water,
- in the third round will also be only one match, so we need another 5 bottles of water.
So in total we need 20 bottles of water.
In the second example no participant will move on to some round directly.
题意：N个参赛选手，每场比赛给运动员b瓶水，裁判一瓶水，运动员没人p条毛巾，求一共要多少瓶水和毛巾？
n个运动员需要n-1场比赛，故需水（n-1）*2*b+（n-1）瓶；0毛巾直接为p*n；
超级水～～～
