合并区间（Python）

看完示例直接上手敲，调了半天才发现是 类一维数组，笑死，根本通不过 ：）

# class Interval:
#     def __init__(self, a=0, b=0):
#         self.start = a
#         self.end = b

#
# 
# @param intervals Interval类一维数组 
# @return Interval类一维数组
#
class Solution:
    def merge(self , intervals ):
        i, intervals = 0, sorted(intervals, key=lambda x: x.start)
        while i < len(intervals) - 1:
            if intervals[i].end >= intervals[i + 1].start:
                intervals[i].end = max(intervals[i].end, intervals.pop(i + 1).end)
            else:
                i += 1
        return intervals
