Actual 2024 Twitter Coding Questions & Solutions

DSA Coding Problems (2024)

Q1: Tweet Feed Generation - 2024 Real Question

Problem: Generate a personalized tweet feed from multiple sources efficiently.

Solution (Java):

public List<Tweet> generateFeed(User user, int limit) {
    PriorityQueue<Tweet> feed = new PriorityQueue<>((a, b) ->
        Long.compare(b.timestamp, a.timestamp));

    // Add tweets from followed users
    for (User followed : user.getFollowing()) {
        feed.addAll(getRecentTweets(followed, limit));
    }

    // Extract top N tweets
    List<Tweet> result = new ArrayList<>();
    while (!feed.isEmpty() && result.size() < limit) {
        result.add(feed.poll());
    }

    return result;
}

Time Complexity: O(n log n)
