What do you have so far? If you notice, if the user enters 5, then it will grow to five in length and then descent in length, so you must have a loop that increases the length until it is what the user had entered and then decrease the length until it is 1 again. You can figure out how to nest these loops in a certain order to make this happen.

Welcome aboard,

 

Which programing language? You could do it in one loop only too, but it would be a little more complicated.

 

Anyway, declare which programing language you are using, ask for this post to be moved  to that language's forum, and post what code you do actually have. :)

Two nested for loops.
