UVA10815 安迪的第一个字典 Andy's First Dictionary
作者:互联网
凌晨给卡了输入,应该是我少考虑一些情况了
晚上再写卡了一会输出
还是不太明白lrj 老师为什么放在set那里,vector,map也可以做,然后借这个机会学了set
vector:
// AC one more times #include<iostream> #include<vector> #include<algorithm> #include<string> #include<map> using namespace std; int main() { string op; vector<string> a; char s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if( s < 'a'|| s > 'z' ) { continue; } else { op+=s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if(s>='a'&&s<='z') op+=s; else if(s<'a'||s>'z') { a.push_back(op); op.clear(); break; } } } } sort(a.begin(),a.end()); a.erase(unique(a.begin(),a.end()),a.end()); for (auto iter=a.begin();iter!=a.end();iter++) cout<<*iter<<endl; return 0; }
map:
// AC one more times #include<iostream> #include<vector> #include<algorithm> #include<string> #include<map> using namespace std; int main() { string op; map<string,int> a; char s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if( s < 'a'|| s > 'z' ) { continue; } else { op+=s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if(s>='a'&&s<='z') op+=s; else if(s<'a'||s>'z') { a[op]++; op.clear(); break; } } } } for(auto it : a) { cout<<it.first<<endl; } return 0; }
set
// AC one more times #include<iostream> #include<vector> #include<algorithm> #include<string> #include<map> #include<set> using namespace std; int main() { string op; set<string> a; char s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if( s < 'a'|| s > 'z' ) { continue; } else { op+=s; while((s=getchar())!=EOF) { if(s<='Z'&&s>='A') s+='a'-'A'; if(s>='a'&&s<='z') op+=s; else if(s<'a'||s>'z') { a.insert(op); op.clear(); break; } } } } for(auto it : a) { cout<<it<<endl; } return 0; }
