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. 用归并排序的思想。 /*** Definition for singly-linked list.* str
把k个有序链表merge成一个有序的链表 Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. 使用优先队列,先把所有不为空的链表头放到优先队列中,然后将最大的一个poll()出来,如果这个最大的节点再原链表中有下一个节点那么把它的下一个节点放
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. 解题分析: 对于此题目,应该先加一个头结点,然后依次比较两个有序的 list 然后将比较,将小的连接
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
Description 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. Solution 将两个有序链表合并成一个链表。(定义一个头结点,方便返回) /**
描述: 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. 分析: 如果第一个链表为空,则返回第二个链表如果第二个链表为空,就返回第一个链表(都为空会返回空
