July 2011 Challenge Winners!

1 min read

Hi CodeCheffers,

The July Challenge 2011 is over!

The July Contest saw some big names battle it out at the top spots. We saw some last minute changes in Indian Ranking from Ravi Kiran who managed to bag the top spot from India and Tomek Czajka who bagged the Global spot. Overall a good contest, a fair bit of difficulty mixed with some easy problems gave this problem set a good balance.

Before we move on to the next section of the blog post, a special mention of the people who made this contest possible:

David Stolp, Ivan Mistreanu, Ashwin Jain, Ashar Fuadi and Gennady were the problem setters while  Shilp Gupta was the diligent tester of this month’s contest.

  1. Possible small UI features:
    1. In the scoreboard, if two scores are close but not equal, add as many digits as necessary to show the difference. For example, the top of the scoreboard this time would be:1. tomek 6.000002. hanshuai 5.99999
    3. chmel_tolstyi 5.99998
    4. Oleg 5.99987
    5. pperm 5.9952
    6. cgy4ever 5.9947
    7. s.max 5.994  (which I believe means “between 5.9935 and 5.9945”, so 3 digits are enough).
    Alternatively, just increase from 3 digits to 6.

    2. Show scores in the “Successful submissions for this problem” table on the problem page.

    3. For some reason my name appears in 3 different formats in various places: “tomek”, “Tomek Czajka”, “Tomasz Czajka”. No big deal. Maybe I changed it at some point (to the less formal “Tomek”) and it didn’t get updated everywhere?

    1. My example scoreboard got mangled. It was supposed to be

      1. tomek 6.00000
      2. hanshuai 5.99999
      3. chmel_tolstyi 5.99998
      4. Oleg 5.99987
      5. pperm 5.99526. cgy4ever 5.99477. s.max 5.994
