solution with python:

t =int(input()) 

for _ in range(t):
    n = input()
    list1 = [n[i] for i in range(len(n)) if i % 2 == 0]
    c= ''.join(list1)
    print(c,end=' ')
    list2 = [n[i] for i in range(len(n)) if i % 2 != 0]
    d= ''.join(list2)
    print(d)

Solution in Java with StringBuilder:

public class Solution {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int length = scanner.nextInt();
        scanner.nextLine();

        for (int i = 0; i < length; i++) {
            String inputString = scanner.nextLine();
            
            StringBuilder even = new StringBuilder();
            StringBuilder odd = new StringBuilder();
            
            for (int j = 0; j < inputString.length(); j++) {                
                if (j % 2 == 0) {
                    even.append(inputString.charAt(j));
                } else {
                    odd.append(inputString.charAt(j));
                }
            }
            
            System.out.println(even.toString() + " " + odd.toString());

        }

        scanner.close();
    }
}
