Easy

Question

Given a list of meeting intervals with start and end times, where the times are represented by integers, return whether there are any conflicting meetings.

If one meeting is scheduled to end at the same time another meeting starts, those two meetings are not considered conflicting.

Meeting Rooms I Example 1

Input: meetings = [[0, 2], [4, 6], [2, 3]]

Output: False

The meetings do not conflict with each other.

Meeting Rooms I Example 2

Input: meetings = [[1, 3], [5, 7], [3, 5], [0, 2]]

Output: True

The meetings at [0, 2] and [1, 3] conflict with each other.

Meeting Rooms I Example 3

Input: meetings = [[3, 4]]

Output: False
