Meeting Rooms II · Coding Interview Practice

Meeting Rooms IIGiven an array of meeting time intervals [start, end), return the minimum number of conference rooms needed so that no two overlapping meetings share a room.Constraints

1 <= intervals.length <= 10^4

intervals[i].length == 2

0 <= start < end <= 10^6

A meeting that ends at time t frees its room for a meeting that starts at t

Examples

Input: intervals = [[0,30],[5,10],[15,20]] Output: 2

Input: intervals = [[7,10],[2,4]] Output: 1

Input: intervals = [[1,5],[5,10],[2,6]] Output: 2
