I know there are multiple other threads on this but I can't wrap my head around why it
public int[] practice_5(List<int> items)
{
if (items == null)
{
return null;
}
else
{
List<int> items_sorted = items.OrderBy(p => p).ToList();
return items_sorted;
}
}
So I have sorted the list of items correctly. I'm assuming but no matter what workaround I try, it won't return it because it can't convert type List<int>
to int[]
?
Do I have to convert the variable items_sorted
before returning?
Try this
public int[] practice_5(List<int> items)
{
if (items == null)
{
return null;
}
else
{
return items.OrderBy(p => p).ToArray();
}
}
or if you want a full refactor, and assuming C# 6.0 or higher.
public int[] practice_5(List<int> items)
{
return items?.OrderBy(p => p).ToArray();
}
