252 Meeting Rooms
252. Meeting Rooms
题目： https://leetcode.com/problems/meeting-rooms/
难度 : Easy
思路：
学了一下如何根据attribute 来sort object intervals.sort(key = lambda interval : interval.start)
AC 代码
# Definition for an interval.
# class Interval(object):
# def __init__(self, s=0, e=0):
# self.start = s
# self.end = e
class Solution(object):
def canAttendMeetings(self, intervals):
"""
:type intervals: List[Interval]
:rtype: bool
"""
n = len(intervals)
if n < 2 : return True
intervals.sort(key = lambda interval : interval.start)
for i in range(1,n):
if intervals[i].start < intervals[i-1].end:
return False
return True
