Programmers’ Challenge

By Nice Silk Man

Note: Source code files accompanying article are located on MacTech CD-ROM or source code disks.

The Rules

Here’s how it works: Each month there will be a different programming challenge presented here. First, you must write some code that solves the challenge. Second, you must optimize your code (a lot). Then, submit your solution to MacTech Magazine (formerly MacTutor). A winner will be chosen based on code correctness, speed, size and elegance (in that order of importance) as well as the postmark of the answer. In the event of multiple equally desirable solutions, one winner will be chosen at random (with honorable mention, but no prize, given to the runners up). The prize for the best solution each month is $50 and a limited edition “The Winner! MacTech Magazine Programming Challenge” T-shirt (not to be found in stores).

In order to make fair comparisons between solutions, all solutions must be in ANSI compatible C (i.e., don’t use Think’s Object extensions). Only pure C code can be used. Any entries with any assembly in them will be disqualified (except for those challenges specifically stated to be in assembly). However, you may call any routine in the Macintosh toolbox you want (i.e., it doesn’t matter if you use NewPtr instead of malloc). All entries will be tested with the FPU and 68020 flags turned off in THINK C. When timing routines, the latest version of THINK C will be used (with ANSI Settings plus “Honor ‘register’ first” and “Use Global Optimizer” turned on) so beware if you optimize for a different C compiler. All code should be limited to 60 characters wide. This will aid us in dealing with e-mail gateways and page layout.

The solution and winners for this month’s Programmers’ Challenge will be published in the issue two months later. All submissions must be received by the 10th day of the month printed on the front of this issue.

All solutions should be marked “Attn: Programmers’ Challenge Solution” and sent to Xplain Corporation (the publishers of MacTech Magazine) via “snail mail” or preferably, e-mail - AppleLink: MT.PROGCHAL, Internet: progchallenge@xplain.com, CompuServe: 71552,174 and America Online: MT PRGCHAL. If you send via snail mail, please include a disk with the solution and all related files (including contact information). See page 2 for information on “How to Contact Xplain Corporation.”

MacTech Magazine reserves the right to publish any solution entered in the Programming Challenge of the Month and all entries are the property of MacTech Magazine upon submission. The submission falls under all the same conventions of an article submission.

Everyone likes anagrams. If you’ve ever had an anagram program and run your friends’ names through it then you know how excited people get when they see what their name can spell when the letters are rearranged. It’s one of those little things that computers can do that impresses non-computer people like my mom more than any amount of awesome 3-D rendering or clever computer animation. This month’s challenge is to write a fast anagram routine.

The prototype of the function you write is:

/* 1 */

unsigned long Anagram(inputText, 
 wordList, outputFile)
Str255  inputText;
FILE    *wordList;
FILE    *outputFile;

InputText is a Pascal string containing the text to anagram. It will be all lowercase letters (a..z) and may contain spaces, which you should ignore (i.e. your anagram may contain more or fewer spaces; it doesn’t matter). WordList is a standard C input stream containing the dictionary of valid words you can use to make your anagrammed output. The words in the dictionary will be all lowercase and sorted from ‘a’ to ‘z’ (and there will be about 20,000 of them). There is a 0x0D byte between each word. You should keep reading words from the stream until you reach the end of file. OutputFile is a standard C output stream that you should write your anagrams to, each one separated by a 0x0D byte. The return value of the function is the number of unique anagrams that were sent to the outputFile.

Good luck and Happy New Year!

TWO MONTHS AGO WINNER

Of the 11 entries I received for the Present Packing challenge, nine worked correctly. Congrats to James Goebel (location unknown) for having the highest average number of presents packed. James previously won the ASCII85 Encode challenge and now he is tied in a 3-way tie for the most number of 1st place Challenge showings.

This challenge was judged based on the highest average number of packages packed. The times and code+data sizes are given for interest only. Numbers in parens after a person’s name indicate how many times that person has finished in the top 5 places of all previous Programmer Challenges, not including this one.

My apologies for not considering that it would be nice if you could rotate a present 90 degrees as you packed it. Several people who entered wrote to me and asked me about that before entering. Unfortunately, Donald Knipp (location unknown) didn’t ask me and just assumed that he could rotate the presents. But since the storePresProc had no way of knowing that he had rotated them he ended up putting presents on top of each other, which invalidated his entry. I’m not happy about disqualifying Donald’s otherwise clever entry but I must in order to be fair to those who were told they couldn’t rotate. In the future, I urge everyone to e-mail me if something is ambiguous or if there are questions about what assumptions you can and cannot make in your solutions.

Here’s James’ winning solution. My apologies for removing some whitespace and comments in order to fit it in this column; James’ unedited code is on the source code disk.

/* 2 */

/* PackPresents() by Clement James Goebel III.
 This code accepts a number of presents one after another and
 attempts to store as MANY as possible
 in its storage area. 
 This routine starts with an array describing the expected 
 distribution of data and then slowly changes to use an array
 that describes the sizes of observed presents as the process
 continues. These arrays are used to decide which presents 
 are too big and should not be stored as they will cause us
 to throw away smaller 
 presents latter. The routine is slow 
 and methodical as it trys to pack presents into the smallest 
   spaces it can find. It also does an ok job of guessing which 
 packages to discard, a function that might not really be 
 needed with evenly distributed data sets. But the goal was
 to pack the most, so you can't be too careful. The matrix 
 that keeps track of stored presents contains zeros where 
 presents are stored, and all other locations contain a value
 that represents the amount of free space that is contiguous
 to that location. We will always try to fill small holes 
 first, a better way might be to look for presents that are
 half the size of the hole, but that would require many more
 special cases. And when placing presents we will always try
 to get as many surfaces to touch as possible.
