"So you thought you knew C?"

Perplexed! is over! Thanks for participating. Scoreboard and explanations (on problem pages) are now available

introduction:

Perplexed! is an online programming contest aimed to explore the depth of C language. Here to win you need not to submit the code with the most efficient algorithm but should be more efficient according to constraints based on limited use of keywords or tokens. The event is of 12 hours so keep improving the code till the event ends. The scoring is relative and your improved code will not only enhance your score but may also decrease of others.

So be ready to test your C skills.

rules:

  1. It is an individual event. To participate in this contest, you only need to register on the website.
  2. Open to all students and professionals.
  3. The contest will last 8 hours and will consist of 6 to 8 problems.
  4. Programming Language - C. All codes will be compiled using gcc 4.4.1 compiler with:
    gcc -O2 -Wall -x c file.c
  5. #define and typedef are not allowed. All C functions are allowed by default.
  6. You can't include any header file. Although, you are allowed to use any function from C Standard library
  7. Maximum of 1000 submissions are allowed for a problem.
  8. Scoring - Participants are ranked according to Total Score
    • Absolute Score for the problem is calculated based on the specified scoring scheme. For e.g. here is a sample scoring scheme:
      Absolute Score = 1000000 / ( 5*S + 2*C + 10*K + 3*O )
      where,

      S = Number of semicolons ;
      C = Number of non-whitespace characters
      K = Number of keywords
      O = Number of commas

    • Relative Score for a problem is calculated based on the scoring scheme as follows:
      Relative Score = (Problem Points * Your Absolute Score for Problem)/(Highest Absolute Score for the problem)
    • Total Score is the sum of Relative Scores for all the problems correctly solved.
    • A problem is said to be correctly solved if it produces correct output for all the inputs of Judge in given time.
  9. Organisers may ask for the explanation of any solution submitted by you, failure to which may lead to disqualification.

submission process:

The user needs to submit only a c code i.e. only files with extension '.c'. Before submission, the user should be able to find the absolute score of his/her code based on the criteria for that very problem.


judging criteria:

This is separate for each problem as explained in the rules.
