Judges' comments:
|
|
|
|
Compile. Try:
|
|
|
|
echo 4 | baruch
|
|
echo 7 | baruch
|
|
|
|
This program reads an integer between 4 and 99 from the stdin.
|
|
|
|
NOTE: The original program did not have a newline at the end of
|
|
the file. We added a final newline to the file to make
|
|
unpacking easy.

Selected notes from the author:
|
|
|
|
The goal of this work was to write a program that solves the
|
|
classic n-queen problem, with a board size of up to 99x99, while
|
|
keeping the program as short as possible.
|
|
|
|
The program finds all possibilities to place N chess queens on
|
|
a NxN chess board so that no queen is in range of any other queen
|
|
(not in the same column row or diagonal). For each solution the
|
|
chess board and the place of the queens is printed to stdout.
|
|
|
|
|
|
This program is about as simple and as readable as possible.
|
|
To make things even more simple we used a very limited subset of C:
|
|
|
|
No pre-processor statements
|
|
Only one, harmless, 'for' statement
|
|
No ifs
|
|
No breaks
|
|
No cases
|
|
No functions
|
|
No gotos
|
|
No structures
|
|
|
|
In short, it contains no C language that might confuse the
|
|
innocent reader. :-)
|
|
|
|
|
|
This program demonstrates the claim that in C, any program
|
|
can be written using a single 'for' statement, as long as it is
|
|
long enough..
|
|
|
|
The authors further note:
|
|
|
|
For PC users:
|
|
In order to compile the program under Turbo-C or MSC, 'int '
|
|
should be inserted at the beginning of the program.
|
|
For better looking results it is recommended to replace the " #Q"
|
|
string with " \261\2".
