0分代码，路过的大佬求指正orz。

代码

#include<iostream>
#include<cstring>
#include<string>
#include<map>
#include<vector>
using namespace std;

        if(t==string::npos) t=cmd.size();
        string temp=cmd.substr(s,t-s);
        str.push_back(temp);
        s=t+1;
    }
}

map<string,string> anylize(vector<string> str){
