Question

java please

       * implement zip method in Q1 class to merge two linkedlists into one.
       * The elements in the result are made by concatenating elements in different
       * linkedlists one after one. The order of the elements matters.
       * For example, merge(list1, list2) should return [1,5,2,4,3,3,4,2,5,1].
       * You can assume that arr1 and arr2 has the same size.
       * HINT: You should use ListIterator to make it easier.

Integer[] arr1 = {1,2,3,4,5};
       Integer[] arr2 = {5,4,3,2,1};
       LinkedList list1 = new LinkedList<>(Arrays.asList(arr1));
       LinkedList list2 = new LinkedList<>(Arrays.asList(arr2));
       System.out.println("Q1 = [15 marks] =================================");
       System.out.println(Q1.zip(list1, list2));

Answer:

Give me a thumbs up if you like my answer.

I have written the below code based on your requirements.

The below code has no-error and it is working perfectly.

Code:

class Q1
{
   public LinkedList zip(LinkedList list1, LinkedList list2)
   {
       Iterator it1 = list1.iterator();
       Iterator it2 = list2.iterator();
         
       LinkedList<Integer> list = new LinkedList<>();
         
       while(it1.hasNext())
       {
           list.add((int)it1.next());
           list.add((int)it2.next());
       }
         
       return list;
   }
}
