Problem B
List of Conquests
Input:standardinput
Output: standard output
Time Limit: 2 seconds

In Act I, Leporello is tellingDonna Elvira about his master's long list of conquests:

``This is the list of the beauties my master has loved,a list I've made out myself: take a look, read it with me. In Italy six hundredand forty, in Germany two hundred and thirty-one, a hundred in France,ninety-one in Turkey; but in Spain already a thousand and three! Among them arecountry girls, waiting-maids, city beauties; there are countesses, baronesses,marchionesses, princesses: women of every rank, of every size, of every age.''(Madamina, il catalogo è questo)

AsLeporello records all the ``beauties'' Don Giovanni ``loved'' in chronological order,it is very troublesome for him to present his master's conquest to othersbecause he needs to count the number of ``beauties'' by their nationality eachtime. You are to help Leporello to count.

Each following line, with at most75 characters, contains a country (the first word) and the name ofa woman (the rest of the words in the line) Giovanni loved. You may assume thatthe name of all countries consist of only one word.
