As soon as you know how to write a recursive function,
the usual constructs like (if), (do), etc., and the
different datastructures available (lists, arrays,
different kinds of numbers, including infinite precision,
etc.), and how to deal with these datastructures (read
the value of a list element (a "cons") == (car elt) ;
read the next element of a list element == (cdr elt) ;
build a new list element == (cons car-part cdr-part), etc.),
you know everything you need, and the kernel of mandatory
things to know is quite small.

The rest is a matter of practice...

Best, Henri
