at first glance, it works, but incorrectly... 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. */
    String word1 = "Hacker";
    String word2 = "Rank";

    char[] arr1 = word1.toCharArray(); 
    char[] arr2 = word2.toCharArray(); 
    print1(arr1);
    System.out.println();
    print1(arr2);

}

public static void print1(char[] array) {
    for(int i = 0; i < array.length; i++) {
        if(i %2 == 0) {
            System.out.print(array[i]);
        }
    }
    System.out.print(" ");
    for(int in = 0; in < array.length; in++) {
        if(in %2 != 0){
            System.out.print(array[in]);
        }
    }
}

}
