Interesting approach using streams in Java:

import java.io.; import java.util.; import java.util.stream.IntStream; import java.util.stream.Collectors;

public class Solution {

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 sc = new Scanner(System.in);
int test = sc.nextInt();
while(test > 0 ) {
    String text = sc.next();
    String evenString = IntStream.range(0, text.length())
    .filter(i -> i%2==0)
    .mapToObj(i -> String.valueOf(text.charAt(i)))
    .collect(Collectors.joining());

    String oddString = IntStream.range(0, text.length())
    .filter(i -> i%2 != 0)
    .mapToObj(i -> String.valueOf(text.charAt(i)))
    .collect(Collectors.joining());

    System.out.println(evenString +" " + oddString);
    test--;
}
sc.close();
}

}
