Solution: Top K Frequent Words
Explore a solution approach using tries and bucket sort to identify the top K most frequent words from a list. Understand how to count word frequencies, organize words by frequency, and retrieve results sorted by frequency and alphabetically, while analyzing 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.
Constraints:
words.lengthwords[i].lengthknumber of unique words in the list words[i]consists of lowercase English letters.
Solution
This solution utilizes the trie data structure and bucket sort method to find the top k elements in a list. It achieves this by combining a bucket sort technique (which groups words based on their frequencies), a trie (which stores words in an organized manner), and a frequency map (which counts the occurrences of each word). ...
