Hi Vishesh, dry-run your code for a sample test-case. And you have not taken the number of testcases as an input. You need to take the number of testcases as an input before the for loop.

Hey Vishesh, there are some mistakes in your code

  • You haven’t taken input for t.
  • when you are adding nodes at head3->next you are not traversing till the tail of the linked list head3 to add the new node at the last. Basically, everytime you are updating only the second node of the head3 linked list.
