Leetcode: Word Frequency

Word Frequency



Similar Problems:


Write a bash script to calculate the frequency of each word in a text file words.txt.

For simplicity sake, you may assume:

  • words.txt contains only lowercase characters and space ‘ ‘ characters.
  • Each word must consist of lowercase characters only.
  • Words are separated by one or more whitespace characters.

For example, assume that words.txt has the following content:

the day is sunny the the
the sunny is is

Your script should output the following, sorted by descending frequency:

the 4
is 3
sunny 2
day 1

Note:
Don’t worry about handling ties, it is guaranteed that each word’s frequency count is unique.
