题意：
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：先将区间按照每个start的值来排序，排好序以后判断一个区间的start值是否处在前一个区间中，如果在前一个区间中，那么合并；如果不在，就将新区间添加。
代码：
# Definition for an interval. # class Interval: # def __init__(self, s=0, e=0): # self.start = s # self.end = e class Solution: # @param intervals, a list of Interval # @return a list of Interval def merge(self, intervals): intervals.sort(key = lambda x:x.start) length=len(intervals) res=[] for i in range(length): if res==[]: res.append(intervals[i]) else: size=len(res) if res[size-1].start<=intervals[i].start<=res[size-1].end: res[size-1].end=max(intervals[i].end, res[size-1].end) else: res.append(intervals[i]) return res
