First Round Question: You are given two linked lists and two integers i and j (i <= j). You need to replace the nodes from index i to j (0-based) in the first linked list with the entire second linked list and return the updated list. Example: Input: List1: 1 -> 2 -> 3 -> 4 -> 9 -> 6 List2: 4 -> 5 -> 10 -> 7 -> 3 i = 2, j = 4 Output: 1 -> 2 -> 4 -> 5 -> 10 -> 7 -> 3 -> 9 -> 6
