题目描述

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).

说明

In the first example will be three rounds: 1. 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), 2. in the second round will be only one match, so we need another $ 5 $ bottles of water, 3. 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.
