Program / Task Name:

   Unique Word Count




Point Value:




Task Description

Ever wonder how many unique words are in a section of text?

Write a program to count the number of unique words in a section of text.

There are two special rules to consider while creating your program:

  • Words separated by a hyphen should be counted as one word (self-employed should be counted as one word), and

  • The case of a letter does not matter (The and the are considered the same word, and would only count once towards the total word count).

You can also assume that:

  • The section of text in will not be longer than 10,000 characters, and

  • No single word will be longer than 80 characters.

The only punctuation used are periods (.), commas (,), question marks (?) and semicolons (;)

Program Input

The section of text to process is in and might look something like this:

Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead who struggled here have consecrated it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here.  It is for us the living rather to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us; that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion; that we here highly resolve that these dead shall not have died in vain, that this nation under God shall have a new birth of freedom, and that government of the people, by the people, for the people shall not perish from the earth.

Program Output

After processing the section of text, output the number of unique words to the screen as follows:

There are 137 unique words.
