So overall it’s O(NlogN).How many meeting rooms do we need at least in order to accommodate all the meetings?In the above example, apparently we should return true for the first question since (1, 4) and (2, 6) have overlaps. Once all the intervals are over, the maximum number of meeting room needed will be the maximum value in the array. With all the analysis above, it shouldn’t be hard to solve the follow-up question. Also, some examples can simplify the problem and make it easier to get the essence.There are basically two suggestions here.
Suppose we use interval (start, end) to denote the start and end time of the meeting, we have the following meeting times: (1, 4), (5, 6), (8, 9), (2, 6).The meeting room scheduling problem was asked by Facebook very recently and there are quite a few similar problems.It seems that only 2 rooms are needed to handle the case where timestamp covers 3 intervals. I used to interview people with a similar problem and I’ve seen that quite a few candidates tended to enumerate “all cases” with tons of if-else clause. Meeting room scheduling problem, there are N meetings with starting time and ending time specified by a pair of integers (S,T). Go over the points one by one in order.
We can go through each interval and increase the reference count in the array. Each meeting has a integer value v and we use vector V to represent the values. Given a list of meeting times, checks if any of them overlaps.
Whenever you get stuck, you should consider trying few examples to understand how you can solve the problem as a human. Room Availability Lightbar. Many people like to write code while thinking, which won’t really work in an interview since you don’t have much time.

Plan yours with desk management for physical distancing.A weekly look at workplace trends and office inspiration.Robin uses in-app reminders and room display cues to give prospective meeting attendees an opportunity to confirm (or delete) scheduled meetings shortly before they happen.Taking steps to reduce no-show meetings in the workplace helps cut back on costs, save employee time and improve overall office productivity. For instance, another popular question is to merge a list of intervals that might have overlaps.
This is just what I was looking for. There is one meeting room in a firm.
First, it’s always recommended to start coding after you are confident enough about your solution. There is an integer number T denoting the ending time of a day. For the follow-up question, we need at least 2 meeting rooms so that (1, 4), (5, 6) will be put in one room and (2, 6), (8, 9) will be in the other.The biggest thing in this post is to try with examples. def kWay( A, k, overlap ) : """ A = list of meeting IDs, k = number of rooms, overlap[ meeting ID m ] = set of meetings overlapping with m """ if k == 1 : # only 1 room: all meetings go there yield [ A[:] ] elif k == len(A) : # n rooms and n meetings: put 1 meeting per room yield [ [a] for a in A ] else : for partition in kWay( A[1:], k, overlap ) : # add new meeting to one existing room for i, ci in enumerate( partition ) : isCompatible = …
This is because for a given timestamp if there are N unclosed start point in front it, this timestamp must be covered by N intervals.If you can have an extra array with one element for each hour, you need not sort the intervals. If you try with several examples and draw them on a paper, you will realize how obvious it is.There’s another way to do that. Suppose we use interval (start, end) to denote the start and end time of the meeting, we have the following meeting times: (1, 4), (5, 6), (8, 9), (2, 6).In the above example, apparently we should return true for the first question since (1, 4) and (2, 6) have overlaps.
