Problem 1641. ABBREVIATION

In the swecond test case, you have:
x ='The Propose is to Make ABBREBIATION';
y_correct = 'T P M A ';
Are "is" and "to" to be ignored, or should the rule be "Only abbreviate words that begin with capital letters?"

In this problem it is assumed that every word in the input string with more than two letters starts with an uppercase letter. All the test cases in the examples have this convention.

I hate regexes because I cannot handle them :-)
