A common preprocessing step in many natural language processing tasks is text normalization, wherein words are converted to lowe

rcase, extraneous whitespace is removed, etc. Write a function normalize(text) that returns a normalized version of the input string, in which all words have been
converted to lowercase and are separated by a single space. No leading or trailing whitespace should be present in the output.

>>> normalize("This is an example.")
'this is an example.'
>>> normalize(" EXTRA SPACE ")
'extra space'
