Hello guys, I didn't find any other solution yet. In my tests it's everything correct, but the check has some problems.. Is there any other alternative way?

Error in de/codegym/task/task04/task0436/Solution.java on line 20

Lösung

In the task example the input list is this: 2, 4 And the example output is this: 8888 8888 - But with the same input list, the output of your program: 88 88 88 88 So: The right form is 2*4 or 4*2? :)

Well, I already was able to find another solution, but I had to google "for-loop inside for" :/. Normally my first solution should work without any problems..

package de.codegym.task.task04.task0436;


/*

import java.io.*;

public class Solution {

    static int n,m;
    static String str = "8";

    public static void main(String[] args) throws Exception {
        //schreib hier deinen Code
        readParams();

        for (int i=1;i<=n;i++){
            for (int j=1;j<=m;j++) {
                System.out.print(8);
            }
            System.out.println();
        }

    }

    static void readParams() throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        n = Integer.parseInt(bufferedReader.readLine());
        m = Integer.parseInt(bufferedReader.readLine());
    }
}
