코드 버퍼를 사용한 입출력 문제입니다. 막 속도 200ms 나오는 사람들 있는데, 그건 FastIO라고 본인들이 입출력 최적화해서 쓰는거라 굳이 알고리즘 풀 때 사용은 안해도 됩니다. 필요하다면 그 때 찾아보고 사용하시면 됩니다. import java.io.*; import java.util.StringTokenizer; public class Main { public static void main(String[] args) throws IOException { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); int T = Integer.parseInt(br.readLine()); StringTokenizer st; St..
