Learn MoreHere we are talking about filtering list items again :). I got two comment suggesting the use of yield return.
James Curran said:
Don’t build a new list if you don’t have to.
private static IEnumerable EvenSlicker_FilterPositiveItems(IEnumerable t)
{foreach(int n in t)
if (n > 0)
yield return n;
}
The advantage is if you try using the method this this:
foreach(int n in FilterPositiveItems(myList) {…}
Your way is O(2N) while mine is O(N)
