21. Merge Two Sorted Lists (python) Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input:1->2->4, 1->3->4Output:1->1->2->3->4->4 利用链表的思想,先创建个空链表p,用于...
1 Linked List 和 Python 基础操作 1.1 链表原理 数组之后,链表是第二种基础的数据存储结构。和数组的连续存储不同,链表是的存储方式更加灵活,可以连续也可以不连续。不连续的存储单位通过上一个元素的”next“指针指出,也就是说,单个存储单位不仅存储元素的值,还存储下一个单位的地址信息。

You are given the heads of two sorted linked lists list1 and list2. Merge the two lists in a one sorted list. The list should be made by splicing together the nodes of the first two lists. Return the head of the merged linked list. Example 1: 代码语言:javascript 代码运行次数:0 运行...
You problem is a pretty basic Python problem: "Iterate trough two lists in parallel. Add the items of both list sequentially to the list of results." Thanks a lot! I can imagine that Python requires a different way of thinking/solving problems. And I already see that some tasks are way...
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 依次拼接 复杂度 时间O(N) 空间 O(1) 思路 该题就是简单的把两个链表的节点拼接起来,我们可以用一个Dummy头,将比较过后的节点接在这个Dummy头之后。
