질문있습니다.

c++ 로 짠 코드인데 자꾸 오답 처리 되는데 어디서 오답처리
되는지 잘 모르겠네요 ㅠㅠ 도와주세요

~~~ c++
#include
#include

using namespace std;

int Operation(map& number, string a, string b, char op) {

switch(op) {

    case '+':
        return number[a] + number[b];
        break;
    case '-':
        return number[a] - number[b];
        break;
    case '*':
        return number[a] * number[b];
        break;
    default:
        return -1;
        break;
}

};

int main() {

map<string, int> number;
map<int,string> answer;
vector<string> output;

number["zero"] = 0;
number["one"] = 1;
number["two"] = 2;

    int ret = Operation(number,a,b,op);     
    if(ret < 0 || ret > 10) {
        output.push_back("NO");
        continue;
    }
    string temp = answer[ret];
    sort(temp.begin(),temp.end());
    sort(c.begin(),c.end());
    if(temp.compare(c) == 0)

    else
        output.push_back("NO");     
}
