Coding - Meeting Rooms

Problem Statement

We need to determine if a person can attend all the meetings in a given array of meeting time intervals without any conflicts. Each meeting time interval is represented as a pair of integers [start, end], where 0 <= start < end <= 10^8.

Here are the key points to consider:

1. Meeting Intervals: Each meeting is defined by a start time and an end time.
2. No Conflicts: A meeting is considered to have a conflict if there is any overlap between its time interval and another meeting's time interval.
3. Edge Cases: Meetings that start and end at the same time are not considered conflicts.

Examples

Example 1: Input: intervals = [[0,30],[5,10],[15,20]] Output: false Explanation: The meetings [0,30] and [5,10] overlap from time 5 to 10.

Example 2: Input: intervals = [[7,10],[9,12]] Output: true Explanation: The meetings [7,10] and [9,12] do not overlap because the start time of the second meeting is after the end time of the first meeting.

Example 3: Input: intervals = [[0,0],[2,5],[8,10]] Output: true Explanation: The meetings [0,0], [2,5], and [8,10] do not overlap.

Constraints

• 0 <= intervals.length <= 10^4
• intervals[i].length == 2
• 0 <= start_i < end_i <= 10^8

Hints

1. Sorting: Sort the meeting intervals based on their start times. This will help in efficiently checking for conflicts.
2. Iterate and Compare: After sorting, iterate through the sorted intervals and compare the end time of the current meeting with the start time of the next meeting to check for conflicts.

Using these hints, you can implement an algorithm to determine if a person can attend all the meetings without any conflicts.
