Need to modify the word occurrence algorithm

[Prince326]

The following program counts the occurrence of words in a string but, it also counts extra spaces in the string as words. Need to modify it so, it won't count the extra spaces as words

Can you please create a doctest that fails because we are counting incorrectly?
