in reply to Improving a palindrome script...

Hi chinamox,

I would not call those major challenges ...

To test whether a string $str is 4 or more characters: 

if (length($str) >= 4) {
    # ...
}

To convert a string $str to lowercase (without "resorting to a regex"): 

my $lower = lc $str;

[download]

Is that what you need?

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/

    Thanks for those two little chunks of code! I am still quite new to Perl so these arn't really known to me yet. This is also why regexs still give me the willys!

      Perl's functions are listed in perlfunc. They are grouped in categories, so you should have been able to find your answers very fast.
