[Java] 백준 단계별 풀기 1 (10712번, 1000번, 1001번, 10998번, 10869번, 10430번, 2588번)

 

*Java는 코드 제출할 때 class 명을 Main으로 설정하고 제출해야 컴파일 에러가 안난다.

 

10712번_

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("|\\_/|");
		System.out.println("|q p|   /}");
		System.out.println("( 0 )\"\"\"\\");
		System.out.println("|\"^\"`    |");
		System.out.println("||_/=\\\\__|");	
	}
}

 

1000번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A, B;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		System.out.println(A+B);
	}
}

 

1001번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A, B;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		System.out.println(A-B);
	}
}

 

10998번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A, B;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		System.out.println(A*B);
	}
}

 

1008번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		double A, B, C;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		C = A/B;
		System.out.println(C);
	}
}

 

float A,B,C했다가 틀림

float = 소수점 9번째 자리에서 반올림(8번째 까지) 출력.

doube = 소수점 16번째 자리까지 출력.

 

 

10869번_

 

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A,B;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		System.out.println(A+B);
		System.out.println(A-B);
		System.out.println(A*B);
		System.out.println(A/B);
		System.out.println(A%B);
	}
}

 

10430번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A,B,C;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		C = scan.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);
	}
}

 

2588번_

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int A,B,C,D,E;
		Scanner scan = new Scanner(System.in);
		A = scan.nextInt();
		B = scan.nextInt();
		C = A*B;
		System.out.println(A*(B%10));
		System.out.println(A*(B/10%10));
		System.out.println(A*(B/100));
		System.out.println(C);
	}
}
