::I guess the FD of an empty list should just be another empty list then? These corner cases always get you. --[[User:Mwn3d|Mwn3d]] 07:39, 11 January 2008 (MST)
:::Yes, that's the way to handle receiving an empty list. (A similar "corner case" has been discussed [[Talk:Maximum_subarray|here]].) <br>One of the things I appreciate about [[J]] is how many of these exception-situations have been resolved within the language itself. In this instance both the single-element and empty-list possibilities require no specific code. --[[User:TBH|TBH]] 09:45, 11 January 2008 (MST)
:The formula given '''Bn = An+1 - An''' only applies to lists of two or more elements. It could be argued that it is more correct to signal an error condition when given a list of less than two elements to work on.--[[User:Paddy3118|Paddy3118]] 04:42, 27 August 2008 (UTC)
It is very nice to see the [[Python]] entry. Studying it has improved my grasp of that language. --[[User:TBH|TBH]] 09:45, 11 January 2008 (MST)
