Solution: Top K Frequent Words
Explore how to determine the k most frequent words from a list by combining trie data structures and bucket sort. Understand how to count word frequencies, organize words by frequency using tries, and efficiently retrieve the results sorted by frequency and lexicographical order. This lesson guides you through implementing this solution with optimal time and space complexity.
We'll cover the following...
Statement
Given a list of strings words and an integer k, return the k most frequently occurring strings.
Note: The result should be sorted in descending order based on frequency. If multiple words have the same frequency, they should be sorted in lexicographical order.
