Re: filtering an array

in reply to filtering an array

Well, what have you tried?

There is, of course, more than one way to do this. One way is to use grep:

my @after;
@after = grep { !/[GT]/ } @positions;

which is, in essence,

my @after;
foreach @positions {
    push(@after, $_) if (!/[GT]/);
}

I tend to use parenthesis where perl's syntax doesn't require them, but that's just me. I find they frequently improve readability.
