Actual 2025 Twitter Coding Questions & Solutions

DSA Coding Problems (2025)

Q1: Trending Topics Algorithm - 2025 Real Question

Problem: Calculate trending topics based on tweet frequency and engagement.

Solution (Java):

public List<String> getTrendingTopics(int limit) {
    Map<String, Integer> topicCounts = new HashMap<>();

    // Count topic mentions
    for (Tweet tweet : getAllRecentTweets()) {
        for (String topic : extractTopics(tweet)) {
            topicCounts.put(topic, topicCounts.getOrDefault(topic, 0) + 1);
        }
    }

    return topicCounts.entrySet().stream()
        .sorted((a, b) -> Integer.compare(b.getValue(), a.getValue()))
        .limit(limit)
        .map(Map.Entry::getKey)
        .collect(Collectors.toList());
}
