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
一、问题描述: Given a collection of intervals, merge all overlapping intervals. For example, Given [1,3],[2,6],[8,10],[15,18], return [1,6],[8,10],[15,18]. 二、解决思路: 针对间隔,按照start从小到大排序。(重写了sort方法)
