Bug Report for https://neetcode.io/problems/merge-k-sorted-linked-lists
Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.
I see test 2 and test 3; the difference between them is that test 2 passes an empty list, but test 3 passes a list with an empty list, but I am getting just an empty list. I think the problem is in the serializator, which converts JSON data and passes it into the function we are testing.

Take a look at "input" and "stdout". I am sure that this is not the correct behavior because my solution wouldn't pass this test.
Thanks for everything you are doing!
Let me know if you need more information. I will be happy to help!
