Hi and welcome to the Pre-ONI Programming Contest 2nd edition!
This contest was organized by myself with the help of some people who
created programming tasks. This year the ones that helped are:
Vlad Dascalu - student - first year at Politehnica Bucuresti
Ionut Fechete - 10th grade at Spiru Haret - Suceava.
Stefanita Fechete - student - first year at Politehnica Bucuresti
If you have questions about the tasks, mail them to the guy who created
the program. Vlad's address is jocuri@softhome.net and Ionut's address is
f_dany@eminem.com. My mail is addictedtoprogramming@yahoo.com. Stefan's
address is f_steff23@yahoo.com.
Some rules
The rules to this contest are very simple. You
are given some programming tasks and you have to solve them using C or C++ or
Pascal. You have to create only one source file pertask. Your solutions will
be compiled using gcc,g++ or fpc under Linux. They will be run against a
series of test cases and will be scored acordingly. Each task is worth 100
points.
If the source code doesn't compile, you get 0 points for that tasks. Else
each correctly solved test case will be worth 100/N points, where N is the
number of test cases used. To correctly solve a test case, your program will
have to finish with exit status 0 before the time limit and will have
to output at the standard output the correct answer. If these conditions are
not met, you get 0 points for a test case.
This is an ONI preparation contest. There is no point in cheating. For
the contest to be fair, you should not use anything but your brain and your
compiler's help system to solve a task. Also note that the contest will be
open for an entire day (from wednesday 6p.m. GMT+2 to tuesday 6.p.m. GMT+2)
in order to have as many people as possible participating.
However, you should only devote as much as 6 hours to solving the tasks.
This should be enough to solve all the tasks. However, I can't stop you from
using more time is you want.
How to send the solutions (QUITE IMPORTANT)
For each task, you have to write one source file. The file should be named
after the problem's ID and its extention should be one of .c for C language,
.cc for C++ language or .p for Pascal. The task IDs begin with 19001 and
end with 19008. Put all the source codes in a .zip archive (not .ace, not
.rar but .zip).
To send the solution write me a mail at addictedtoprogramming@yahoo.com. The
subject line should be "contest" and inside the message you should write your
name and anything else you think I should know. Don't forget to attach the
.zip file. The entire .zip file should be no longer than 30KB. If it is
bigger or it isn't .zip, I will delete it and you won't get graded. Please
attach the file in binary mode. I don't feel like uudecoding files.
Some more details (IMPORTANT)
Please note that all the tasks read input from stdin and write to stdout.
Your program is not allowed to open any other file. If it does, you will be
disqualified. You are not allowed to write anything to stderr -- make sure
you disable debugging output before sending the solution.
If you write a program that tries to undermine system security you will
get disqualified and added to the shame list.
The programs will be compiled using the following command lines:
for C: gcc -O2 -static -o output sourcecode
for C++: g++ -O2 -static -o output sourcecode
for Pascal: fpc -Xs -O2 -o output sourcecode // hopefully this is correct
Final hints (VERY IMPORTANT)
The grading machine is a 1Ghz Athlon running RH Linux 8. gcc is version
3.2. fpc is version 1.0.6. The timelimit in each task is for the realtime --
but no other processes will be run at the same time.
Before sending the solutions, make sure your source code compiles and
that it doesn't do anything stoopid like writing extra debugging output,
waiting for a keystroke, reading/writing to other files.
Make sure your program uses only as much memory as allowed (the limit
is different for each task and written in each task text).
If everything goes fine, the results will be displayed on tuesday,
7p.m GMT+2, an hour after the contest is over.
If I left something out or you would like to say something to me,
feel free to contact me at addictedtoprogramming@yahoo.com. However,
don't flame me or something because I hate that.
