obfuscated weixi This is actually the outcome of a game of perl golf. The task was to print a hexadecimal representation of pi, where the digits are not calculated en bloc but one after the other. The longer the program runs the more digits it produces. <p> However, the algorithm itself is rather obfuscated already and reducing the number of characters for the perl golf resulted in another level of obfuscation. So I thought the obfuscation section would be the right place for it to post anyway. <code> $|=print 3.2;sub O{8*($@-$_)+(1,4,5,6)[$:]};sub o{(-4,2,1,1)[$:]/O};while($,=++$@){for$:(0..3){ for (0..$@) {for$" (($/=1) ..$_){ ($/*=16) %=O}; $,-=$/ *o}$, -=16** $_*o for-6..- 1}printf "%x",$,* 16%16} </code>
