Betreff: Need some help
please
Hi,
I need to define a function called
safetail; it's like tail except that this one maps the empty list to the empty
list. It has to be defined using the following:
- a conditional
_expression_
- guarded equation
- pattern matching
It's probably quite simple, but I
am struggling on this, so help would be appreciated.
Thanks
Raj
