- the total area of all rooms;
- the total area of all bedrooms;
- the cost of the flat.
The first line contains two integer numbers n (1 ≤ n ≤ 10) and c (1 ≤ c ≤ 100000) - number of rooms in the flat and the cost of one square meter, respectively.
Each of the following n lines contains an integer number
ai (1 ≤
ai ≤ 100) 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".
