Congratulations – You’ve Qualified for Google Code Jam 2009!



Congratulations honour.neat! You’ve qualified for Round 1 of Google Code Jam 2009!

We have decided to allow all contestants to compete in all three Round 1 sub-rounds, regardless of their specified preferences. The top scoring 1000 contestants in each subround will advance to Round 2, and are no longer able to compete in the remaining subrounds.

For example, if you participate in Round 1A, and do not advance, you may continue to participate in Round 1B and also in Round 1C. If you do advance in round 1A, you will advance to Round 2, and you will not be able to participate in Round 1B or 1C. If you advance in Round 1B, you may not participate in Round 1C

The dates and times for Round 1 are as follows. You can find your local time at

Round 1A: September 12, 2009 at 01:00 UTC
Round 1B: September 12, 2009 at 16:00 UTC
Round 1C: September 13, 2009 at 09:00 UTC

Each round will last 2 hours and 30 minutes.

えーっと、ざっと読んだところだとラウンド 1にはサブラウンドがあって、each subroundの上位1,000人がラウンド 2に行ける。Round 1Aで合格したら1Bや1Cは受けられない。つまり、3,000人が通過するわけだ。1Aで余裕合格しちゃった人が1Cを荒らすことはない。


Round 1Aが土曜日の11:00から。
Round 1Bが日曜日の1:00から。
Round 1Cが日曜日の18:00から。
