I just did the Google Code Jam thing. This was the first time ever that I used TopCoder, so I had to spend the first ten minutes just trying to figure out the interface. The first problem for 300 points was something to do with decibels. I took heck of a lot longer to solve this problem than I should.
The second problem was for 600 points and the problem mentioned something about 'topography' but I have no idea what it had got to do with the actual problem. It was an easy problem which is why I am wondering whether I solved it correctly or not! I did get the correct answers for all the 3 examples, though.
I scored 496.11 points and TopCoder says that I am in the 25th position in Division 1.
Update : Looks like I made it to the next round.
