題意就是有N個pl妹子，然後每行第一個單詞是妹子的國籍，後面是妹子的名字。

你的任務就是統計相同國籍妹子的個數，然後按字母表順序輸出。

我首先把所有的國籍都讀入，然後用qsort()按字母表順序排序。

In Act I, Leporello is telling Donna Elviraabout his master‘s long list of conquests:

``This is the list of the beauties my master has loved, a list I‘ve madeout myself: take a look, read it with me. In Italy six hundred and forty, inGermany two hundred and thirty-one, a hundred in France, ninety-one in Turkey;but in Spain already a thousand and three! Among them are country 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)

As Leporello records all the ``beauties‘‘ Don Giovanni``loved‘‘ in chronological order, it is very troublesome for him to present hismaster‘s conquest to others because he needs to count the number of``beauties‘‘ by their nationality each time. You are to help Leporello tocount.

Input

Each following line, withat most 75 characters, contains a country (thefirst word) and the name of a woman (the rest of the words in the line)Giovanni loved. You may assume that the name of all countries consist of onlyone word.
