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]. 解答 这题首先根据起始点对Interval进行排序,然后从头开始遍历Interval,对遍历到的每一个Interval(用current表示),将其终止点作为界限,检查其后的Interval的起始点是否小于或等…

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]. 合并重叠区间 class Solution(object): def merge(self, intervals): """ :type intervals: List[Interval] :rtyp…

Merge Intervals 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]. 记返回数组为ret. 先对start排序. 然后对每两个interval(记为a,b),判断是否需要合并. 如果不需要合并(没有交集),则把a装入ret,将b继续往后. 如果需要合并(有交…

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]. 看起来感觉不像hard类型的题目,不过要注意的一点是这里给出的数据不一定会像上面这样按照顺序来进行排序,所以处理前首先要按照一定的规则处理一下,写一个functor来进行比较,用struct即可,排序后这个范围就很好确…

problem: 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]. Hide Tags Array Sort 题意:给定数组区间,合并有覆盖或者相邻的区间 thinking: (1)一開始我想到用hash table的方法,开一个总区间跨度的数组.对于有区间覆盖的数…

Given a collection of intervals, find the minimum number of intervals you need to remove to make the rest of the intervals non-overlapping. Note: You may assume the interval's end point is always bigger than its start point. Intervals like [1,2] and…
