Each of the following n lines contains an integer number ai (1ai100) and a word ti - the area of i-th room and its type, respectively. Word ti is one of the following: "bedroom", "bathroom", "kitchen", "balcony", "other".

#### Output

The first line should contain one integer number - the total area of all rooms of the flat. The second line should contain one integer number - the total area of bedrooms of the flat. The third line should contain one real number - the cost of the flat with precision not worse than 10-6.
