string을 잘 split하고 reverse 하면 풀 수 있는 문제

 

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <sstream>
using namespace std;

vector<string> split(string input, char delimiter) {
	vector<string> answer;
	stringstream ss(input);
	string temp;

	while (getline(ss, temp, delimiter)) {
		answer.push_back(temp);
	}

	return answer;
}

int main() {

	int n;
	cin >> n;
	cin.ignore();
	for (int i = 0; i < n; i++) {
		string s;
		getline(cin, s);
		vector<string> v = split(s, ' ');

		for (int i = 0; i < v.size(); i++) {
			reverse(v[i].begin(), v[i].end());
			cout << v[i] << " ";
		}
		cout << "\n";
	}
	
	return 0;
}
