Your job is to tidy up a list of words that appear in a string. The words are separated by one or more spaces. Remove all words that are one or two letters long and make sure that exactly one space separates all the words. Strings will be made up only of letters and spaces. Spaces should not appear at the beginning or end of your output string.

Example:

 inStr =  'ours is  not to   reason why';
 outStr = 'ours not reason why';

This problem is tricky! Better add more test cases and rescore. E.g., 'aaa bb'
