[백준 알고리즘] 2675번 문자열 반복(Python 3, Java)

 

 

<Python 3>

n = int(input())
for i in range(n):
    P, S = input().split()
    for j in range(len(S)):
        print(S[j]*int(P), end='')
    print()

<Java>

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

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        int T = Integer.parseInt(br.readLine());
        StringBuilder sb = new StringBuilder();

        for(int i=0; i<T; i++){
            StringTokenizer st = new StringTokenizer(br.readLine(), " ");
            int repeat = Integer.parseInt(st.nextToken());
            String line = st.nextToken();

            for(int j=0; j<line.length(); j++)
                for(int k=0; k<repeat; k++)
                    sb.append(line.charAt(j));
