会议室

“会议室”问题的详细指南和 Python 实现。

问题陈述

简单

给定一组会议时间间隔,其中 Intervals[i] = [starti, endi],确定一个人是否可以参加所有会议。

编写一个函数 canAttendMeetings(intervals: List[List[int]]) -> bool

约束条件
  • 0 <= len(intervals) <= 10^4
  • intervals[i].length == 2
  • 0 <= starti < endi <= 10^6

示例

Example 1
Input
intervals = [[0,30],[5,10],[15,20]]
Output
False
Explanation

Overlap exists between meetings.

Example 2
Input
intervals = [[5,8],[9,15]]
Output
True
Explanation

No overlapping meetings.

Need a Hint?
考虑使用特定于间隔的数据结构,例如集合或堆。
Edge Cases to Watch
  • 空输入结构
  • 单元素输入
  • 大数值范围
