It's Saturday night.
You're a puzzle solver and have no social life, so you amuse yourself by spelling out the first 1010 integers.
You know, like ... one, two, three, ... twenty-one, ... four hundred thirty-two, ... nine thousand five hundred thirteen, ... two million ninety thousand three hundred five, ... four billion three hundred seventeen million, forty-five thousand two hundred twenty-nine, ...
Then you hit Sort to get them in alphabetical order. [Edit: spaces and hyphens are ignored.]
What's the first odd number in your sorted list?
