Can you please check if this error still occurs in 0.0.6?

@ecmel Do you have a source file or better a project that I can use to reproduce this?

gorkem picture gorkem on 25 Nov 2016

@gorkem Can not reproduce with 0.0.7 so far.

ecmel picture ecmel on 28 Nov 2016

In that case, I am closing this one. @ecmel reopen if you can reproduce.

Still facing this issue with version v.0.0.13 With the following Solution.java file

import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

    /** 
     * Reads a string and separates the odds and even characters 
     * @param   str     The input string
     * @return  Two groups: odds and evens separated by a space
     * */    
    public static String strParts(String str){
        char[] charArr = str.toCharArray();
        StringBuilder odds = new StringBuilder();
        StringBuilder evens = new StringBuilder();
        for(int i=0; i<charArr.length; i++){
            if( (i % 2) == 0 ){
                odds.append(charArr[i]);
            }else{
                evens.append(charArr[i]);
            }
        }
        return odds.toString() + " " + evens.toString();
    }

    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
         Scanner in = new Scanner(System.in);

         /* number of T test cases */
         int T = in.nextInt();

         if (T >= 1 && T <= 10){

            String[] strs = new String[T];

            /* Read from STDIN */
            for(int t = 0; t<T; t++){
                String str = in.next();
                if(str.length() <= 10000){
                    strs[t] = str;
                }
            }

            /* print output to STDOUT */
            for(int i = 0; i<strs.length; i++){
                System.out.println(strParts(strs[i]));
            }

         }

         /* free the scanner resource */
         in.close();
    }
}

Errors showing up on output console as I type in the editor:
