Toasted Sesame Bagels,

Thank you to everyone who participated in this months contest. It was a close race, with lead changes occurring up until the the last hour. Congratulations to our winners:

India:
1. Harpreet Singh – Rs. 22000
2. Surendra – Rs. 13750
3. Ajay Somani – Rs. 11000
4. Keshav Dhandhania – Rs. 5500
5. Ashutosh Mehra – Rs. 2750

US:
1. Balakrishnan Varadarajan – $440
2. bcloud – $275
3. Josh Metzler – $220
4. ploh – $110
5. Tomasz Czajka – $55

A special mention should be given to Stephen Merriman (2nd), stolis (5th), Anton Lunyov (6th) and RoyaumER (9th) for finishing in the top 10 globally. To all our international participants, we are planning a contest in the next month or two where you will be eligible for prizes.

We’d also like to apologize for changing the time limit for HX a few days before the contest was over. We have really tried to avoid making changes during a running contest but in this case we though that the time limit was too strict and too much emphasis was placed on proper I/O. We will do our best to make sure that these types of issues don’t come up in the future.

If you want to give back to the CodeChef community and help up-and-commers to get better, we encourage you to contribute to a tutorial, links or tips in our wiki (if you do a good job, we’ll also send you some books).

There will not be another contest in October, the next contest is November 1st and will be our (now) standard 10 day format. We will be holding a second contest (most likely a team based ACM-ICPC style competition) in the later part of next month.

Tomorrow, we will be updating the banner, making solutions public, providing contest statistics and test cases.

Contest Statistics:

Length of Contest Unique Visitors Unique Participants Total Number of Submissions Percentage of user who have solved at least one problem

If you have any feedback on the contest, or how we can make the site better, please let us know.

Cheers,

Amit (Chef)

  1. Yun Zhou beat me on the challenge problem – 1402300 to 1402683. We only tied in the scoreboard where results are rounded to 3 decimal places, so I think he should get the full 2nd place prize.

  3. Josh, you are ever the gentleman. :)Congratulations! I'll be curious to read your and other winners' solutions when I have a chance. Is there a place where people discuss the problems after the contest?One thing I'm still puzzled at is the fact that the test server seemed to run 4x slower than my 1.8 GHz laptop. (I don't think cache was an issue.) Is this typical?

  5. I think the judge solution checker program was too slow for the tie breaker :). I got a 4.xx second acc and it still took a lot of time for the server to give me the result.
