LeetCode刷题笔记（Non-overlapping Intervals）

刚刚刷了一道题感觉难度还行，不过这道题既可以用线性规划法解，也可以用贪心算法解，下面就分享一下刚刷的这道题吧！题目如下：题意分析：给定一个包含若干区间的集合，请尽可能少的删掉子区间以确保剩余的区间不重叠，最后返回删掉的区间个数即可。方法一（贪婪算法）先按照区间结尾排序，每次选择结尾元素最小且与前一个区间不重叠的区间，最后将区间的集合长度减去组成最长不重叠区间的区间个数（即res值）的结果返回即可。

LeetCode Non-overlapping Intervals(dp,greedy)

问题：给定一个区间的集合，找到需要移除区间的最小数量，使剩余区间互不重叠。注意:可以认为区间的终点总是大于它的起点。区间[1,2]和[2,3]的边界相互“接触”，但没有相互重叠。思路：第一种方法使用动态规划，首先基于左端点排序。用dp(i)表示在第i个区间时不重叠区间的数。则有dp(i)=max(dp(j)+1),其中j属于[0,i),并且j与i不重叠。也可以基于右端点排序。第二种方法使用贪心法。
