    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]);
        }
    }
}

    }

    In Python:

    def index_characters(string):
    evens = [letter for index, letter in enumerate(string) if index % 2 == 0]
    odds = [letter for index, letter in enumerate(string) if index % 2 != 0]
    print("".join(evens), "".join(odds))
    
if __name__ == "__main__":
    n = int(input())
    
    for _ in range(n):
        string = input()
        index_characters(string)

    In Python

    def test_case(): s = input() e=[] o=[] for k in range(len(s)): if k%2==0:
    e.append(s[k]) else: o.append(s[k]) s= f"{"".join(e)} {"".join(o)}" return s

    for i in range(int(input())): print(test_case())
