11656번: 접미사 배열

배열로 정렬해도 되고 PQ를 이용해도 됩니다.

 

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.PriorityQueue;

public class Main {
    
    static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    static StringBuilder sb = new StringBuilder();

    public static void main(String[] args) throws Exception {

        String str = br.readLine();
        PriorityQueue<String> pq = new PriorityQueue<>((o1, o2) -> {
           return o1.compareTo(o2);
        });
        for (int i = 0; i < str.length(); i++) {
            pq.offer(str.substring(i, str.length()));
        }

        while (!pq.isEmpty()) {
            sb.append(pq.poll()).append("\n");
        }

        System.out.print(sb.toString());

    }

}
