ROUND 1 CODING CHALLENGE
Name : Odd
Summary: Take as input a single line of integers in base 10, output the
odd numbers in the input line (in base 10) in order, and terminate.
Par : 284 (note: took me ~4 hours to find this not-fully optimized solution)
Details: For this starting exercise, input will assume to be sanitized to be:
- A single line of text, followed by a newline (10).
- Only consist of numeric characters [0-9], with a single space
between each integer.
- Contain at least 1 integer.
- The first character will be a digit. The last character
immediately before the newline will be a digit.
- Should work for arbitrary length of input, though with size
of array and runtime limits, only up to 80 characters will
be expected to run.
Output will:
- produce 1 line consisting of the odd numbers from the input
separated by spaces, terminated by a newline, and exit.
- Output must be produced/triggered by the newline, not an EOF.
Sample run:
$ bf odd.b
codesize: 284

Run for 25355 steps.
**************************************************************************
Brainfuck Golf - full Contest Regulations.
1. All persons start the game with 0 points. The winner of the contest
is the first person to earn 200 points as described here. All
first-class persons except the Contestmaster CAN earn points in this
Contest; 'person' hereafter refers to first-class persons only.
2. All solutions must be written in Brainfuck (BF). BF will be
implemented in general as described here:
http://esolangs.org/w/index.php?title=Brainfuck&oldid=32694
The Contestmaster will use the following code to evaluate programs:
http://pastebin.com/YKaRdgvb
The comments at the beginning of this code describe implementation-
specific issues for this contest. The contestmaster CAN change the
code used for evaluation With Notice, by publishing a link to the
new code; e is encouraged to do so only in the case of bugs or
implementation issues.
3. The Contestmaster starts a round by announcing a coding challenge
(the problem), and a program length (measured in BF characters) for
eir implementation of a working program (Par). The Contestmaster
should not over-optimize eir solution. A Working program is a BF
program solves the problem for the (possible unannounced) test cases
of the problem developed by the Contestmaster. The length is the
number of BF characters (excluding whitespace or comments) in the
program.
4. For the purpose of this contest, "Immediately" means within 4 days.
5. All code submissions are made privately to the Contestmaster. Upon
receipt, the Contestmaster SHALL immediately privately inform the
submitter of success/failure, and is encouraged to make helpful
suggestions.
6. The first person to submit a working solution of any length (the
Leader) receives 10 points, plus 1 point for each character eir
solution is under par (if it is under par). The receipt of this
entry begins the shootout period. The Contestmaster shall
immediately announce the receipt and length of the solution (the
lead-establishing entry). The shootout period ends 7 days after
this announcement.
7. The Target for the shootout period is Par or the length of the
Leader's Submission, whichever is less.
8. When the shootout period ends:
a. A person's Final Shot is the single, shortest-length WORKING
program that e submitted during the Shootout period. The
lead-establishing entry is also considered to be a final shot,
unless the leader submits a shorter working solution during
the shootout period.
b. The single person (if any) who submits the shortest final shot
earns 20 points.
c. Any person who submits a final shot earns 5 points, plus, if the
shot is less than the target, 1 point for each character that
the shot is less than the target. The lead-establishing
entry, if it also the leader's final shot, is not considered for
this particular points award.
d. At the contestmaster's option, e MAY award 10 points to the most
'elegant' solution, for which both coding and comments may be
taken into consideration (although ASCII art in and of itself
is discouraged, commenting and structural flair may count).
e. For the purpose of determining the "first" person to earn 200
points, the points are awarded in the following order: Points
for (b. shortest shot) are awarded first, followed by points
for (c. each person's final shot, awarded in the order each
final shot was submitted) and finally (d. elegance).
9. The Contestmaster SHALL announce awards for a Round, and publish all
working solutions and scores, immediately after the shootout period
ends, thus ending the Round. Immediately after ending a round, if
no person has won the contest, the Contestmaster SHALL start a new
round.
10. The Contesmaster is the primary interpreter of the Regulations of
this contest, and eir interpretations should only be overturned by
the courts if they are arbitrarily or capriciously out of keeping
with the spirit of this contest.
