해결법

방법 1

import java.util.*;

class Solution {
    public List solution(int[] num_list) {
    
        List<Integer> answer = new ArrayList<>();
        
        Arrays.sort(num_list);
        
        for (int i = 5; i < num_list.length; i++) {
            answer.add(num_list[i]);
        }
        
        return answer;
    }
}

• ArrayList

방법 2

import java.util.*;

class Solution {
    public int[] solution(int[] num_list) {
    
        Arrays.sort(num_list);
        
        int n = 5;
        
        int[] answer = new int[num_list.length - n];
        
        for (int i = n; i < num_list.length; i++){
            answer[i - n] = num_list[i];
        }
        
        return answer;
    }
}

• answer[i - n]
  • i는 n과 동일하게, 5부터 시작이기 때문

방법 3

import java.util.*;

class Solution {
    public int[] solution(int[] num_list) {
    
        Arrays.sort(num_list);
        
        int idx = 0;
        
        int[] answer = new int[num_list.length - 5];
        
        for (int i = 5; i < num_list.length; i++) {
            answer[idx++] = num_list[i];
        }
        
        return answer;
    }
}
