To make the problem a little easier, a portion of the code is provided for you in the editor. Note: We recommend completing Java Stdin and Stdout I before attempting this challenge. For each String (where ), print 's even-indexed characters, followed by a space, followed by 's odd-indexed characters. import java.io.*; import java.util.*; public class Solution { public static void main (String [] args) { /* Enter your code here.
