feat: Merge two ArrayLists by pattern List1 + List2 + List1 and print result

🧠 Logic:
- Accepts sizes and elements of two lists from user input.
- Stores elements in `list1` and `list2` using `ArrayList<Integer>`.
- Creates a `mergedList` and adds:
  - All elements of `list1`
  - Then all elements of `list2`
  - Then `list1` again to form the final merged pattern.
- Prints the merged list in a single line.
