Asked in companies
You have been given an array/list 'WORDS' of 'N' non-empty words, and an integer 'K'. Your task is to return the 'K' most frequent words sorted by their frequency from highest to lowest.
Note:
If two words have the same frequency then the lexicographically smallest word should come first in your answer.
Follow up:
Can you solve it in O(N * logK) time and O(N) extra space?
Problem approach
Brute force was to iterate on every collection id/name over every file given and then group them up. That was not an optimized solution.
Optimal way is to use Set to remove duplicates first and then use min heap with custom comparators to sort files by sizes, custom class object to group the files by collections.
