Leetcode 1348. Tweet Counts Per Frequency
Design a class that records timestamps for each tweet name and, given a frequency ("minute"/"hour"/"day") and a time range, returns the number of tweets in each contiguous fixed-size time chunk covering that range. The challenge is to efficiently group timestamps into buckets per tweet name and support many dynamic record/get queries over arbitrary ranges.
