A person can attend all meetings if no two meeting intervals overlap. Meetings ending at time t and starting at time t do not overlap.

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
