排序检索B - List of Conquests

这题题目长不难

每句话第一个单词是国家

输出是统计国家的名字和出现的次数

输出之前要根据国家名字排序

因为要对应国家的名字和次数

用结构体非常方便

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define N 100000
struct list{
char name[2000];
int num;
}s
, ss;

int n, mark, num = 0;
char c[2000], city[2000];
scanf("%d", &n);
getchar();
while (n--) {

for (int i = 0; i < strlen(c); i++)
if (c[i] == ' ') {

In Act I, Leporello is telling Donna 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 hundred and 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 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 questo)

As Leporello records all the \beauties" Don Giovanni \loved" in chronological order, it is very

troublesome for him to present his master's conquest to others because he needs to count the number

of \beauties" by their nationality each time. You are to help Leporello to count.

Input

The input consists of at most 2000 lines. The rst line contains a number

n

, indicating that there will
