The cadr function will do what you want.

(typep thing 'first) will do what you want.

Try defining accessor functions that return particular elements of the list using car and cdr.

Perhaps all the 20-year old legacy systems are so good because 99% of them have already been thrown in a dumpster? At this point, you're really looking at the best of the best. It's easy to be...

Of what use would tokenizing the string be?
The question isn't to reverse the words in a string.

This looks suspiciously like a question intended by a job interviewer to filter out the people...

If you're talking about removing everything in it, that's a really bad idea.

If you mean to free some disk space, you should figure out what's eating it all up. You can also try rm -r /var/tmp/*...

no,no...

Are you sure it's using port 25? Try using PuTTY instead of MS Telnet - it's a far superior program.

It has to do with the magic variables setting. Try using $_REQUEST['id'] and $_REQUEST['lang'] instead.

It looks as though you're trying to write a function that returns a function, which I'm sure is not what you intended. Also, the LET form takes either an atom or a two-element list of atoms. What's...

Actually, never mind. The solution is pretty advanced for someone just learning. Here it is, for educational purposes:

Have you thought about using recursion? After all, the maximum of a list of numbers is the maximum between the first number and the maximum of the rest of the numbers.

Incidentally, my source was an amusing interview
with Ice T, whom I consider to be authoritative in this domain. :)

"getting jiggy with it" means to dress up for the purpose of looking good when you go out.

Try adding this to the end:


print "Press ENTER to exit: "

The READ function will return a lisp object just like the representation in your code, but PARSE-INTEGER only takes strings. You probably want to use READ-LINE instead, which returns only strings.

Use CSS to eliminate any margin and padding of the body tag:


body { margin: 0; padding: 0; }

You are incorrect. Both Common Lisp and Scheme are perfectly good industry languages with wide platform support and usage. For many, including myself, a lisp language is their preferred language.

That won't work, unless I'm reading it wrong...


<?php
$string = '2005-03-IT-31';

} else {

Ok, so what is the question?

It won't work like you want. Try this instead:

<script type="text/javascript" lang="Javascript" src="headerfile.js"/>
<script>
// your script
</script>

It wants to know the directory under which the CD is mounted.

You're on the right track. You want to use the fread() and fwrite() functions with a pointer to an instance of your structure and the FILE pointer.

Yes, that's precisely correct.

I'm sorry, but what is it that you need help with?

Try testing the parents of the current person, then recurse if neither parent has blue eyes.

That won't work in common lisp for a number of reasons. This would, though:

(defun row-and-column ()
'((1 2 3 4 5)
(6 7 8 9 0)
(1 2 3 4 5)
(6 7 8 9 0)
(1 2 3 4 5)))

Have you tried using another mouse? You might also be able to use the accessibility controls to move your mouse if you have the extension enabled.

Try using the CGI module. It makes doing CGI development in Perl extremely easy (at least the CGI bits).

Try this at a command line:

What implementation of lisp are you using? The error should be that I was assumed special, since it wasn't declared with the lambda.
