Need Help??

how come you use ( ) on one abs but not the other? :-)

sub g {(sort{abs$a-$_[1]<=>abs$b-$_[1]}@{$_[0]})[0]} # 44 chars
[download]

Update:
pop and no ref...

sub g {$n=pop;(sort{abs$a-$n<=>abs$b-$n}@_)[0]} # 39 chars
[download]

fantastic - that's exactly half my original

For future reference, I found your spec unclear. In the end I settled on "2 parameters" as being the clearest statement. But it would help in the future if you gave sample test code using the function. Then there can be no doubt. However if I am allowed to rearrange the arguments, I find it more natural that any special arguments should come first in the list. Giving a 38 character solution: `sub g { (sort{abs$a-$_[0]<=>abs$b-$_[0]}@_)[1] }` [download]	[reply] [d/l]

Apologies for my ambiguous description. Please take a look at the update I have made and tell me if I make any more sense. ps. 38 chars - good job! "Argument is futile - you will be ignorralated!"	[reply]
