Now, there are two possibilities for what the maximum possible overlap might be: We can cover both cases in O(n) time by iterating over the intervals, keeping track of the following: and computing each interval's overlap with L. So the total cost is the cost of sorting the intervals, which is likely to be O(n log n) time but may be O(n) if you can use bucket-sort or radix-sort or similar. Cookies Drug Meaning. 2023. Note that the start time and end time is inclusive: that is, you cannot attend two events where one of them starts and the other ends at the same time.
