Don't know why the third condition is failing.
I am getting the output right but its not verifying.
package com.codegym.task.task07.task0717;
import java.util.ArrayList;
import java.util.Scanner;
/*
Duplicating words

public class Solution {
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
ArrayList<String> list = new ArrayList<>();
for (int i = 0; i < 10; i++){
list.add(scanner.nextLine());
}
ArrayList<String> result = doubleValues(list);
for (String i : result){
System.out.println(i);
}
scanner.close();
}
private static ArrayList<String> doubleValues(ArrayList<String> list) {
for (int i = 0; i < list.size(); i++){
list.add(i + 1, list.get(i));
i++;
}
return list;
}
}
