입력된 숫자들 중에서 최솟값과 최댓값을 찾는 문제였다.

문제 풀이

1. Scanner

import java.util.Scanner;
public class Main {
    public static void main(String args[]) {
        Scanner scanner = new Scanner(System.in);
        int N = scanner.nextInt();
        int[] A = new int[N];
        int max = Integer.MIN_VALUE;
        int min = Integer.MAX_VALUE;

        for (int i = 0; i < N; i++) {
            A[i] = scanner.nextInt();
            if (A[i] > max) {
                max = A[i];
            }
            if (A[i] < min) {
                min = A[i];
            }
        }
        
        System.out.printf("%d %d",min,max);
    }
}

2. BufferedReader

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

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        int N = Integer.parseInt(reader.readLine());
        String[] input = reader.readLine().split(" ");
        
        int max = Integer.MIN_VALUE;
        int min = Integer.MAX_VALUE;

        for (int i = 0; i < N; i++) {
            int num = Integer.parseInt(input[i]);
            if (num > max) {
                max = num;
            }
            if (num < min) {
                min = num;
            }
        }
        
        System.out.printf("%d %d", min, max);
    }
}
