Problem 65. Word Counting and Indexing

Created by Cody Team in Community

You are given a list of strings, each being a list of words divided by spaces. Break the strings into words, then return a master word table of all the words and an indexed version of each string.

The master list should have no repeated entries and should be sorted in alphabetical order.


If str_list = {'one two three','two one four zero'}


  • word_table = {'four','one','three','two','zero'}
  • str_index_list = {[2 4 3],[4 2 1 5]}.

Notice that no words are repeated in word_table, and each string in the string_list can be regenerated by referencing into the word_table using the string_index_list.
