sstream을 이용한 문자열 파싱(c++)

#include <vector>
#include <sstream>
#include <iosteam>
#include <string>

int solution(vector<string> lines) {
    stringstream ss;
    vector<vector<string> > v;
    
    for(int i=0; i<lines.size(); i++){
    	ss.str(lines[i]);
        string tmp;
        
        while(ss >> tmp){
            v[i].push_back(tmp);
            cout << v[i].back() << "\n";
        }
        cout << "-----";
    }
}
/*
    ex) 입력 : ["하이 방가", "오늘 뭐해?"]
        출력 : "하이"
              "방가"
              -----
              "오늘"
              "뭐해?"

함수로 구현

#include <vector>
#include <sstream>
#include <string>

vector<string> split(string str, char delimiter) {
    stringstream ss(str);
    string tmp;
    vector<string> v;
 
    while (getline(ss, tmp, delimiter)) {
        v.push_back(tmp);
    }
 
    return v;
}

int solution(vector<string> lines) {
    vector<vector<string> > v;
    
    for(int i=0; i<lines.size(); i++){
        v.push_back( split(lines[i], ' ') );
    }
    
    return answer;
}
