Re: [Pharo-users] Interogation about recursivity or sequential

I propose this as an exercise.
Now I was not aware that we have doubleLinkedList in the system.

I do not get why DoubleLinkedList is packaged in System-Caching and not 
Collections-DoubleLinkedList?

Recursive is often cleaner, sequential is often faster.

There is already a (minimal) DoubleLinkedList in the image ...

Recursivity is usually better to read, understand. However sequential is 
usually more efficient (but harder to implement right).

[Pharo-users] Interogation about recursivity or sequential

2016-01-04 Thread Yann Dubois 
Hello World, Happy new year 2016 !

I actually work on an integration of a double linked list on Pharo and I
have a little interogation.
It's better to use recursivity or senquential algorithm ?
