Given a set of non-overlapping intervals, insert a new interval into the intervals (merge if necessary). You may assume that the intervals were initially sorted according to their start times. Example 1:Given intervals [1,3],[6,9], insert and merge […

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]. 解题思路一: 用两个指针startIndex和endIndex来维护每次添加intervals的start和end的位置,然后分类讨论即可,JAVA实现如下: public List<Interval> merge…

给出一个区间的集合, 请合并所有重叠的区间.示例:给出 [1,3],[2,6],[8,10],[15,18],返回 [1,6],[8,10],[15,18].详见:https://leetcode.com/problems/merge-intervals/description/ Java实现: /** * Definition for an interval. * public class Interval { * int start; * int end; * Interval() { st…

题目 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]. 分析 给定几个区间,要求合并重叠区间,返回结果: AC代码 /** * Definition for an interval. * struct Interval { * int start; * int en…

目录 题目链接 注意点 解法 小结 题目链接 Merge Intervals - LeetCode 注意点 区间是无序的 每个区间start一定小于end 解法 解法一:首先以start的值从小到大来排序,排完序我们就可以开始合并了.先把第一个区间存入ret,然后从第二个开始遍历所有区间,如果与ret中最后一个区间有重叠就更新,否则就直接存入ret.时间复杂度O(n) /** * Definition for an interval. * struct Interval { * int star…

Merge IntervalsGiven 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]. SOLUTION 1: 1. 先使用Comparator 的匿名类对intervels进行排序. 2. 把Intervals遍历一次,依次一个一个merge到第1个interval. 把第1…
