解法一：集合

集合 set 的裸题，了解一下相关 STL 用法，注意像 aaa-bbb 这种文本需要当作 aaa 和 bbb 两个单词。

#include <bits/stdc++.h>

using namespace std;

int main() {
  set<string> text;
  string s, buff = "";
  while (cin >> s) {
    for (auto c : s)
      if (isalpha(c)) buff += tolower(c);
      else if (buff != "") text.insert(buff), buff = "";
    if (buff != "") text.insert(buff), buff = "";
  }
  for (auto word : text) cout << word << endl;
  return 0;
}

#include <bits/stdc++.h>

using namespace std;

int main() {

set<string> text;

string s, buff = "";

while (cin >> s) {

for (auto c : s)

if (isalpha(c)) buff += tolower(c);

else if (buff != "") text.insert(buff), buff = "";

if (buff != "") text.insert(buff), buff = "";

}

for (auto word : text) cout << word << endl;

return 0;

}
