Meeting Rooms
Given an array of meeting time intervals where intervals[i] = [starti, endi], determine if a person could attend all meetings.
Input & Output
Input
intervals — an array of meeting time intervals where intervals[i] = [starti, endi]
Output
true if a person could attend all meetings, false otherwise
Example
Input
intervals = [[0,30],[5,10],[15,20]]
Output
false
Explanation
The meetings overlap, so a person cannot attend all meetings.
Example
Input
intervals = [[7,10],[2,4]]
Output
true
Explanation
The meetings don't overlap, so a person can attend all meetings.
Example
Input
intervals = [[0,30],[5,10],[15,20],[5,15]]
Output
false
Explanation
The meetings overlap, so a person cannot attend all meetings.
Constraints
- 1 <= intervals.length <= 10^4
- 0 <= starti < endi <= 10^6
