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].思路分析:这题关键要想到先对区间排序,然后从前向后扫描,如果下一个没法合并,就添加一个区间;如果可以,还要继续向后看,...

POJ 3680 Intervals
题目链接
题意:给定一些区间,每个区间有一个权值,要求用这些区间去覆盖,每个点最多覆盖k次,问最多得到权值多少
思路:典型的区间k覆盖问题,区间连边容量1,代价-w,然后其他点相邻两两连边,容量k,代价0,跑一下费用流即可
