    Xmas competitions

    It's almost December and it's time for some festive fun.

    Competition 1
    Draw a xmas tree using ASCII art, as demonstrated below.
    The input to the program will be a single command line argument indicating the order
    Eg. xmastree 7

    The judging will be based on the most elegant solution (whatever that means)
    But presentation, comments, layout, etc will score big

    Code:
    Order 0
       /\
    
    Order 1
       /\
      */\*
      /  \
    
    Order 2
       /\
      */\*
      /  \
     */  \*
     /    \
    /      \
    Closing date: Midnight 7/12/2003 (GMT)


    Competition 2
    http://www.night.net/christmas/12-Days.html
    Output the words to the 12 days of christmas
    The program has no command line, nor any input
    Eg. xmassong

    The judging will be based on the best obfuscation of the program.
    The most obscure and convoluted program wins, providing it actually
    produces the required output.
    It you want to centre-align each line, you can if you want, but left-aligned text will also be fine.

    Competition 3
    Santa has a lot of presents to put into his sleigh, and thus he needs
    to optimise how the presents are packed to minimise the wasted space.
    As he is very busy, he doesn't have a lot of time to come up with an answer.

    The following list is a list of dimensions of xmas presents, which must be
    placed into a 1 cubic metre box.
    50 50 50
    50 50 50
    50 50 50
    50 50 50
    The boxes are a list of width, height and depth sizes (in centimetres).
    This example fills the bottom half of the box with the 4 equally sized presents.

    Write a program which fits the presents in the box.

    Since orientation matters inside the box, the results consist of
    - box number
    - bottom-left-back corner (x,y,z)
    - top-right-front corner (x,y,z)

    The program accepts a single command line argument, which is the name
    of the file containing the list of presents (one present per line).
    Eg. xmasbox presentlist.txt

    The calculation function pack_presents() should be clearly identifiable, as I will
    be adding timing code around that function call. You can call it what you
    want, but you need to indicate where I need to add the timing code.
    Something like this is suggested.
    Code:
            /* START TIMER */
            pack_presents();
            /* END TIMER */
    The judging is solely on the time it takes pack_presents() to complete,
    so its generally in your interest to make it stick to the calculations only.
    So make all your input and output separate functions.

    There will be at most 20 presents to be fitted into the box.

    Three separate tests will be performed, which will result in
    - a partially filled box
    - a completely filled box
    - an overfilled box (choose most presents or least wasted space)

    Closing date: Midnight 30/12/2003 (GMT)



    All of these are to be written in ANSI-C or ANSI-C++ only (STL permitted for C++)
    I'll be using gcc/Linux to compile and test code.

    Submission details will follow shortly.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Question on #2. Do you mean to use complicated algorithms or to make the source code complicated to follow (i.o.w: unreadable)?

    It's up to you to decide how best you want to make the code unreadable.

    The second contest ends on my birthday, does that mean my entry automatically wins ?

    I guess we can only use std c/c++, right?

    Question for #2, can we output to a text file, seeing as printing all of it to screen would result in about 4/5 of it not being visible?

    Thanks Salem Saves me a few lines of code. Although ironically I'll be making it horrifically odd and obscure.

    For #3, Is it safe to assume that

    a. None of the boxes may stick out of the top

    b. None of the boxes have dimensions longer than 100cm

    ?

    Do the trees have to look exactly as show in your post?

    Competition 1 question:
    does the amount of sections on the base of the tree equal the order?

    Code:
      /  \
     /    \
    for order 2
    
    and 
       /  \
      /    \
     /      \
    /        \
    for order 4
