How to find k frequent words in a file?

A simple solution is to use Hashing. Hash all words one by one in a hash table. If a word is already present, then increment its count. Finally, traverse through the hash table and return the k words with maximum counts.

How do I find the most frequent words?

How would you find the maximum occurrence of a word in a huge file?

Approach 2: Using Counting Array Approach to find the Top x words

1. Iterate all words and maintain a count inside hash data structure.
2. Traverse the hash and find the with maximum frequency, “second”:100 in this case, then create an array of string with size 100 – this is Big O(x) where x number of unique words in hashmap.

What is top K sort?

The top K elements pattern is a technique that aims to return a given number of the most frequent/largest/smallest elements in a given set. The key data structure of solving the top K elements problems is heap.

How to find the most repeated word in a text file?

In this program, we need to find the most repeated word present in given text file. This can be done by opening a file in read mode using file pointer. Read the file line by line. Split a line at a time and store in an array. Iterate through the array and find the frequency of each word and compare the frequency with maxcount.

How to find the most frequent word in a list?

Given a non-empty list of words, return the k most frequent elements. Your answer should be sorted by frequency from highest to lowest. If two words have the same frequency, then the word with the lower alphabetical order comes first.
