Leetcode Problem 1348. Tweet Counts Per Frequency

1348. Tweet Counts Per Frequency

Leetcode Solutions

Using TreeMap for Efficient Time Interval Queries

  1. Initialize a HashMap where the key is the tweet name and the value is a TreeMap that maps the tweet timestamp to its occurrence count.
  2. Implement recordTweet by inserting the timestamp into the TreeMap for the given tweet name, incrementing the count if the timestamp already exists.
  3. Implement getTweetCountsPerFrequency by determining the size of the time chunks based on the frequency, then querying the TreeMap for timestamps within the start and end time.
  4. Iterate over the queried timestamps, calculating the index of the time chunk they fall into and incrementing the corresponding count.
  5. Return the list of counts for each time chunk.
