for i in range(len(s)):

    For JAVA

    Scanner scan=new Scanner(System.in);

    int N=scan.nextInt();
scan.nextLine();
for(int i=0;i<N;i++){
    String s=scan.nextLine();
    for(int j=0;j<s.length();j++){
        if(j%2==0){
            System.out.print(s.charAt(j));
        }
    }
    System.out.print(" ");
    for(int k=0;k<s.length();k++){
        if(k%2!=0){
            System.out.print(s.charAt(k));
        }
    }
    System.out.println();
}

scan.close();

    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]);
        }
    }
}

    }
