Q:编写程序，使用stable_sort和isshorter将传递给你的elimdups版本的vector排序。打印vector的内容，验证你的程序的正确性。

#include<iostream>#include<vector>#include<algorithm>#include<string>#include<iterator>using namespace std;void elimdups(vector<string> &s);bool isshorter(const string &s1,const string &s2);int main(void){char *p[]={"indicate","apple","red","ramos","apple","rockets","red","world","end","blue","white","wx","misaya","end"};vector<string> strs(begin(p),end(p));elimdups(strs);stable_sort(strs.begin(),strs.end(),isshorter);for(auto i:strs)cout<<i<<' ';cout<<endl;return 0;}void elimdups(vector<string> &s){sort(s.begin(),s.end());auto end_unique=unique(s.begin(),s.end());s.erase(end_unique,s.end());}bool isshorter(const string &s1,const string &s2){return s1.size()<s2.size();}
