I have two set of perl codes. Please let me know which one is best on the parameter such as , memory usage, execution time 

FUNC("test",$flag);

sub FUNC{
print $_[0] if ($_[1]);
}

[download]
My second code is 

Func("test") if $flag);

sub FUNC{
print $_[0];}

[download]
I have this kind of code 4-5 times in my script. I am confused here which one to use considering above parameters. Please help. Also it would be nice if somebody can explain how to calculate this parameters. Also, if there is any more parameter to decide which one to use please mention. Thanks
