Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

xxx,

Thanks again for taking the time to speak with me and for sending me your information.  I'm excited to tell you that we would like to move forward in the process!

One of our coordinators will be emailing you within the next week from an @google.com domain with the date and time of your phone interview.  In the meantime, I've included some preparation materials (below.)

Please note this will be a technical interview that will last for approximately 45 minutes. Google takes an academic approach to the interviewing process. This means that we are interested in your thought process, your approach to problem solving as well as your coding abilities. You may be asked questions that relate to technical knowledge, algorithms, coding, performance, how to test solutions, and perhaps your interest in Google products. The best advice that I can give you is to treat the interview like a conversation, talk through the problems, and please feel free to ask the interviewer if you are not clear with any of the questio
