Solution: Top K Frequent Words

Discover how to implement a solution for identifying the top k most frequent words using trie and bucket sort methods. Understand the step-by-step process, including frequency mapping, organizing words in buckets by frequency, and retrieving sorted results efficiently. This lesson helps you master optimal time and space complexity in handling frequent word extraction.

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:

  • 11 \leq words.length 100\leq 100

  • 11 \leq words[i].length 10\leq 10

  • 11 \leqk \leq number of unique words in the list

  • words[i] consists of lowercase English letters. ...
