[프로그래머스] 배열, 구현, 수학

• 배열 자르기

#include <string>
#include <vector>
#include <algorithm>

using namespace std;

vector<int> solution(vector<int> numbers, int num1, int num2) {
    vector<int> answer(numbers.begin() + num1, numbers.begin() + num2+1);
    return answer;
}

• 외계행성의 나이

#include <string>
#include <vector>

using namespace std;

string solution(int age) {
    string answer = "";
    while(age != 0){
        answer = (char)(age % 10 + 97) + answer;
        age /= 10;
    }
    return answer;
}

• 진료순서 정하기

#include <string>
#include <vector>
#include <algorithm>

using namespace std;

vector<int> solution(vector<int> emergency) {
    vector<int> answer;
    vector<int> v(emergency);
    sort(v.begin(), v.end(), greater<>());
    for(int i=0; i<emergency.size();i++){
        for(int j=0; j<emergency.size(); j++){
            if(v[j] == emergency[i]) answer.push_back(j+1);
            
        }
    }
    return answer;
}

• 순서쌍의 개수

#include <string>
#include <vector>

using namespace std;

int solution(int n) {
    int answer = 0;
    for(int i=1; i<n+1; i++){
        if(n % i == 0) answer++;
    }
    return answer;
}
