I can compile the following code. But when I run the program it gives me a

Here's the error.

core.exception.RangeError@untitled(34): Range violation

As it seems the problem is with the line "pointers[i]=n". What's wrong here? :s
There is no node in pointers as of now, thus pointers[i] can only be a range
violation, whatever i (even 0, which should point to the *first* node).
pointers[i]=n;
would *change* the current element number i. To put a *new* node into pointers,
if that's what you intended, use the '~' appending operator (here in version '~=');
pointers ~= n;
