Meeting Rooms II

Explore how to determine the minimum number of meeting rooms needed to hold overlapping meetings by analyzing interval start and end times. Learn to approach interval problems with sorting and merging methods to optimize space and time complexity.

We'll cover the following...

Statement

We are given an input array of meeting time intervals, intervals, where each interval has a start time and an end time. Your task is to find the minimum number of meeting rooms required to hold these meetings.

An important thing to note here is that the specified end time for each meeting is exclusive.

Constraints

  • 1<=1 <= intervals.length <=103<= 10^{3}
