Shame that, according to its own documentation, it doesn't work!
Usage : my @deranges = derange(@n);
Function: implements !n, a derangement of n items in which none of th
+e
items appear in their originally ordered place.
Example : my @n = qw(a b c);
my @d = derange(@n);
print join "\n", map { join " ", @$_ } @d;
# prints:
# a c b ### Not a derangment; a in it's original position
# b a c ### Not a derangment; c in it's original position
# b c a
# c a b
# c b a ### Not a derangment; b in it's original position
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
