BaekJoon/BOJ [JAVA] 별찍기 - 2_2439 HINT: 2438문제의 응용으로써, 이 풀이는 공백 부분을 직접 " "로 넣어서 풀었다 import java.util.Scanner; public class baekjoon_2439 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.next()); for(int i=1;i

BaekJoon/BOJ [JAVA] 별찍기 - 1_2438 HINT: 반복문을 중첩하자 import java.util.Scanner; public class baekjoon_2438 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.next()); for(int i=1;i

BaekJoon/BOJ [JAVA] 구구단_2739 HINT: 구구단 출력시, 공백은 상관 없는듯 하다 import java.util.Scanner; public class baekjoon_2739 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.next()); scanner.close(); for(int i=1;i

BaekJoon/BOJ [JAVA] N찍기_2741 HINT: for문을 써보자 import java.util.*; public class baekjoon_2741 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.next()); for(int i=1;i

BaekJoon/BOJ [JAVA] 기직N_2742 HINT: 2741의 거꾸로! import java.util.*; public class baekjoon_2742 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.next()); for(int i=num;i>=1;i--){ System.out.println(i); } } }

BaekJoon/BOJ [JAVA] 고양이_10171 HINT: 굳이 힌트라면 \을 주의할것..? public class baekjoon_10171 { public static void main(String[] argc){ System.out.println("\\ /\\"); System.out.println(" ) ( ')"); System.out.println("( / )"); System.out.println(" \\(__)|"); } }

BaekJoon/BOJ [JAVA] 괄호_9012 HINT: stack을 써보자! '('이면, stack에 넣고, ')'이면 stack에서 pop한다. import java.util.*; public class baekjoon_9012 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int num = Integer.parseInt(scanner.nextLine()); int check=1; for(int i=0;i

BaekJoon/BOJ [JAVA] A*B_10998 단계: 사칙연산 도전하기 HINT: 그냥 곱하자 import java.util.*; public class baekjoon_10998 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int a = scanner.nextInt(); int b = scanner.nextInt(); System.out.println(a*b); } }

BaekJoon/BOJ [JAVA] 사칙연산_10869 단계: 사칙연산 도전하기 HINT: 그냥 사칙연산이다 import java.util.*; public class baekjoon_10869 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); int a = scanner.nextInt(); int b = scanner.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); } }

BaekJoon/BOJ [JAVA] A/B_1008 단계: 사칙연산 도전하기 HINT: java의 데이터 형을 유의하자 int, byte, short, long -> 정수형 float, double -> 실수형 import java.util.*; public class baekjoon_1008 { public static void main(String[] argc){ Scanner scanner = new Scanner(System.in); double a = scanner.nextDouble(); double b = scanner.nextDouble(); System.out.println(a/b); } }
