會議室

「會議室」問題的詳細指南和 Python 實作。

問題陳述

簡單

給定一組會議時間間隔,其中 Intervals[i] = [starti, endi],決定一個人是否可以參加所有會議。

寫一個函數 canAttendMeetings(intervals: List[List[int]]) -> bool

約束條件
  • 0 <= len(intervals) <= 10^4
  • intervals[i].length == 2
  • 0 <= starti < endi <= 10^6

範例

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?
考慮使用特定於間隔的資料結構,例如集合或堆。
Edge Cases to Watch
  • 空輸入結構
  • 單元素輸入
  • 大數值範圍
