풀이코드

// 1. Scanner 이용

import java.util.Scanner;

public class Main{
    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);
        
        int A = scanner.nextInt();
        int B = scanner.nextInt();
        int C = scanner.nextInt();
        
        System.out.println((A+B)%C);
        System.out.println(((A%C)+(B%C))%C);
        System.out.println((A*B)%C);
        System.out.println(((A%C)*(B%C))%C);
    }
}

// 2. BuffedReader 사용

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

public class Main{
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        
        String str = br.readLine();
        StringTokenizer st = new StringTokenizer(str, " ");
        
        int A = Integer.parseInt(st.nextToken());
        int B = Integer.parseInt(st.nextToken());
        int C = Integer.parseInt(st.nextToken());
        
        System.out.println((A+B)%C);
        System.out.println(((A%C)+(B%C))%C);
        System.out.println((A*B)%C);
        System.out.println(((A%C)*(B%C))%C);
    }
}

 

📌 풀이 과정

• 입력받은 값 단순 연산
• 나머지 구해야하니 정수형으로 계산
