Yesterday I had to implement [Selection Sort](http://en.wikipedia.org/wiki/Selection_sort)
|
|
for double-linked lists and I had some trouble finding the correct solution
|
|
when it comes to swapping two elements.
|
|
|
|

|
|
code here so others can use it (or even tell me about hidden bugs)
|
|
|
|
I implemented it in Java, so see here:
