Given an array of meeting time intervals where intervals[i] = [starti, endi], determine if a person could attend all meetings.

Example 1:

Input: intervals = [[0,30],[5,10],[15,20]]
Output: false

Example 2:

Input: intervals = [[7,10],[2,4]]
Output: true

Constraints:

  • 0 <= intervals.length <= 104
  • intervals[i].length == 2
  • 0 <= starti < endi <= 106

Python

				
					from typing import List


class Solution:
    def canAttendMeetings(self, intervals: List[List[int]]) -> bool:
        if len(intervals) == 0:
            return True
        intervals.sort()
        for i in range(1, len(intervals)):
            if intervals[i][0] < intervals[i-1][1]:
                return False
        return True


intervals = [[7, 10], [2, 4]]

print(Solution().canAttendMeetings(intervals))
