Hey, be fair to SQLite!
Jacob F.
Let’s let Ruby decide:
class Array
def map_with_index
inject([[], 0]) { |r, a| [r[0] << (yield a, r[1]), r[1] + 1] }[0]
end
alias :mwi :map_with_index
end
class Acronym
TERMS = [
%w{Linux OpenBSD FreeBSD NetBSD},
%w{Apache Lighttpd},
%w{MySQL PostGreSQL SQLite Firebird},
%w{PHP/Perl/Python Ruby LISP},
]
def self.make(*args)
t, fmt = args.dup, ‘and %s’
“%s: %s” % [args.map { |s| s[0,1] }.join, (t << fmt % t.pop;
t.join(’, '))]
end
def self.all(args = [])
ret = []
if args.size == TERMS.size
ret << make(*(args.mwi { |num, i| TERMS[i][num] }))
else
0.upto(TERMS[args.size].size - 1) { |i| ret << all(args << i);
args.pop }
end
ret
end
end
puts Acronym.all

seem to be LAMR, LASR, LAFR, FAMR, FAPR, and FASR.
