Meeting Rooms

Problem: Meeting Rooms

In this problem, all we need to do is sort the intervals and judge neighbors.

Code in Python:

class Solution(object):
    def canAttendMeetings(self, intervals):
        """
        :type intervals: List[Interval]
        :rtype: bool
        """
        intervals.sort(key = lambda x: x.start)

        for i in xrange(1, len(intervals)):
            if intervals[i].start < intervals[i-1].end:
                return False
        return True
