python测试开发20-合并重叠区间(facebook面试题)

面试题

给定区间的列表，合并所有重叠的区间。

Given [1,3],[2,6],[8,10],[15,18],
return [1,6],[8,10],[15,18].

英文原文：

Find the contiguous subarray within an array (containing at least one number) which has the largest sum.

For example, given the array [−2,1,−3,4,−1,2,1,−5,4],
the contiguous subarray [4,−1,2,1] has the largest sum = 6.

参考答案

先将区间按照start的值来排序，再判断区间的start值是否处在前一个区间中，如果在前一个区间中就合并，反之添加新区间。
