Remove hint.html and index.html
As per discussions on GitHub the index.html and hint.html files should be deleted in favour of README.md files (from any .text/.txt/.markdown/.md files which will be turned into README.md in an upcoming commit).

<h2>Judges' comments:</h2>
|
||||
|
||||
<h3>To use:</h3>
|
||||
|
||||
<pre><code>make
|
||||
./prog
|
||||
</code></pre>
|
||||
|
||||
<h3>Try:</h3>
|
||||
|
||||
<pre><code>./prog 128
|
||||
|
||||
./prog_be 128
|
||||
|
||||
./prog 170
|
||||
|
||||
./prog 85
|
||||
</code></pre>
|
||||
|
||||
<h3>Selected Judges Remarks:</h3>
|
||||
|
||||
<p>This tiny one-liner is a bit-twiddlers delight! It does all of the work
|
||||
without looping.</p>
|
||||
|
||||
<p>To understand how it works, a good place to start is to look at the hex
|
||||
value that results when the two magic constants are XOR'ed.</p>
|
||||
|
||||
<p>Once you’ve figured out what happens with one set of constants, how can
|
||||
choosing new constants, but using the same computation generate a reversed
|
||||
result?</p>
|
||||
|
||||
<h2>Author’s comments:</h2>
|
||||
|
||||
<p>Invoke this with a single non-negative integer less than 256, and a useful transformation occurs.</p>
|
||||
|
||||
<h3>Rule 2-ish</h3>
|
||||
|
||||
<p>Exporting the constants B,I,T,S to the makefile allows the code
|
||||
to be compiled for either LE (little-endian) or BE (big-endian) machines(!!),
|
||||
so they are truly configuration parameters, not logic.</p>
|
||||
|
||||
<h3>Notes</h3>
|
||||
|
||||
<p>One <strike>ping</strike> argument only. It will SEGV on zero arguments, and
|
||||
display strange results if more than one argument.</p>
|
||||
|
||||
<p>Small, non-negative integers only. Useful range is 0 .. 511, sorta, for LE; 0 .. 255 for BE.
|
||||
Bonus points if you can explain why the limits work this way.</p>
|
||||
|
||||
<p>ASCII character set, 64-bit long longs are required.</p>
|
||||
|
||||
<p>v,a,r,i,a,b,l,e,s_NAME the operation.</p>
|
||||
|
||||
<p>No loops, no branches?!?</p>
|
||||
|
||||
<h3>Compilation</h3>
|
||||
|
||||
<p>Compiles cleanly under <code>clang -Wall -Weverything -pedantic</code>,
|
||||
but you need to add <code>--include stdio.h --include stdlib.h</code> for the <code>printf</code>(3) and <code>atoi</code>(3).</p>
|
||||
|
||||
<p>On a little-endian machine:</p>
|
||||
|
||||
<pre><code>clang -include stdio.h -include stdlib.h -Wall -Weverything -pedantic -DB=6945503773712347754LL -DI=5859838231191962459LL -DT=0 -DS=7 -o prog prog.c
|
||||
</code></pre>
|
||||
|
||||
<p>On a big-endian machine:</p>
|
||||
|
||||
<pre><code>clang -include stdio.h -include stdlib.h -Wall -Weverything -pedantic -DB=7091606191627001958LL -DI=6006468689561538903LL -DT=1 -DS=0 -o prog.be prog.c
|
||||
</code></pre>
|
||||
|
||||
<p>You might be interested to compile it both ways on the same host, and try:</p>
|
||||
|
||||
<pre><code>./prog 1; ./prog.be 1
|
||||
</code></pre>
