20053번: 최소, 최대 2

코드

package com.company;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

class Main {

    public static void main(String[] args) throws IOException {
        StringBuilder sb = new StringBuilder();
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer st;
        int T = Integer.parseInt(br.readLine());

        for (int i = 0; i < T; i++) {
            int n = Integer.parseInt(br.readLine());
            int max = Integer.MIN_VALUE;
            int min = Integer.MAX_VALUE;
            st = new StringTokenizer(br.readLine(), " ");
            for (int j = 0; j < n; j++) {
                int num = Integer.parseInt(st.nextToken());
                if(max < num)
                    max = num;
                if(min > num)
                    min = num;
            }
            sb.append(min + " " + max +"\\n");
        }
        System.out.println(sb.toString());
    }

}

풀이

입력 받고 min과 max를 비교해나가면 된다.
