Meeting Rooms

---

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
