If you know LINQ well, you should be able to extend it with a custom operator.
Can you write an operator that moves all elements of a sequence that satisfy a predicate to the back of the sequence?
Let me try it.
Iterate through the sequence.
Check the predicate.
Now, what if the element was matched?
We must wait for all other elements to pass before pushing this one to the output.
It is now at the end of the pending list.
Otherwise, yield-return the object.
Once we have exhausted all the elements, the list contains those we were supposed to move to the end.
Let me yield-return the elements from the pending list, and the new operator is complete.
What do you think about this coding technique?
This call moves even numbers to the end.
Follow the link to the long video to learn other aspects of LINQ.
