• Problem1.py: Excellent job! Your implementation is clean, efficient, and handles edge cases well. The use of a helper function (_shift_stacks) is a good practice.
• Problem2.py: Your approach is conceptually sound, but there's a critical bug in the initialization of the hash table. Instead of [ListNode] * self.size, you should initialize each bucket with a new ListNode (e.g., [ListNode() for _ in range(self.size)]). This ensures each bucket is independent. Also, consider adding a check in remove to handle the case where the key is not found.
