Node 1's value is 1, both of its next and random pointer points to Node 2. Node 2's value is 2, its next pointer points to null and its random pointer points to itself. Note: You must return the copy of the given head as a reference to the cloned list. """# Definition for a...

A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. Return a deep copy of the list. 本题题意就是复制链表,注意使用HashMap等结构保存相关信息,这样更加方便。

Finally, the two tabs—tab1 and tab2—have mirrored local history, as they share the same list object under the hood. Ultimately, how you implement shallow and deep copying in custom classes is entirely up to you. Additionally, if you’re using Python 3.13 or later, then you might also...
