[백준 2675] 문자열 반복

문제

2675번: 문자열 반복

 

접근방법

 

간단한 반복문이다. 나중에 String, StringBuffer, StringBuilder관련 포스팅을 적어야지.

 

코드

 

package string;

import java.util.Scanner;

public class Repeat {
	public static StringBuffer sb ;
	public static void addString(char c,StringBuffer sb, int count) {
		for(int i=0;i<count;i++) {
			sb.append(c);
		}
	}
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int T = in.nextInt();
		
		for(int t=0; t<T ;t++) {
			int count = in.nextInt();
			String word = in.next();
			sb = new StringBuffer();
			
			for( int index = 0; index < word.length();index++) {
				char c= word.charAt(index);
				addString(c, sb, count);
			}
			System.out.println(sb);
		}
		in.close();
	}
}
