Meeting Rooms

Detailed guide and Python implementation for the 'Meeting Rooms' problem.

Problem Statement

Easy

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

Write a function canAttendMeetings(intervals: List[List[int]]) -> bool.

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

Examples

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?
Consider using Intervals-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
