Hi,
I was wondering if anyone can guide me on how I should be preparing for the google kickstart competition. I have a bit of basic c++ knowledge, and I am reading competitor's handbook by Antti Laaksonen. I am very confused on how I should be preparing for the competition however. I am just doing random problems, but it does not feel like the most efficent way forward. I am still new to competitive programming, so any input would be appreciated.
Also, as I am new to this site, apologies in advance if this type of question that should not be asked.

Thanks
