I have a method that will generate a random HTML link, but I need to  
have it repeat inside a string interpolation. I need to generate a  
number of random links at the bottom of HTML pages that are being  
generated. I know how to insert the method into the string so it  
inserts a random link there, but I don’t know how to get it to insert 30  
different links instead of just one.

Inside the HTML, it looks like this to just insert one link:

########  
…

Sitemap

  
 #{insertlink}   

... ########

What I don’t know how to do is to get it to do the insertlink method 30  
times in that spot instead of just once. Help, please…?

def foo  
r = []  
30.times do  
r \<\< insertlink  
end  
r.join(’ ')  
end

That would probably make the most sense… but, since I’m still a fetus  
programmer (I’m not even a baby yet \>.\>; ), I didn’t think of doing  
that. :-p Many thanks!

you may use  
string \* 30  
to repeat the string 30 times
