( #3333=superdoc: print w/replies, xml ) Need Help??
Hey... I may be a silly goose but I'd linearly cast it into an associative array and then use the hash to provide O(n) performance at the expense of memory and relatively poor randomness (if there is a such thing as good randomness) for nearly sorted data (based on the internal hashing mechanism) ... like this:
#!/usr/bin/perl -w my @unrandom = ("red", "orange", "yellow", "green", "blue", "indigo", +"violet"); my @ununrand = (); my %temphash = (); my $indX = 0; for ($indX=0;$indX<@unrandom;$indX++) { $temphash{$unrandom[$indX]} = $indX; } @ununrand = keys(%temphash); print "Unn:@unrandom\nRnd:@ununrand\n";
Which prints:
Unn:red orange yellow green blue indigo violet Rnd:blue orange green violet yellow red indigo
Not great but fast anyway. Hope this is cute and werks for someone. TTFN.
