Idiom #257 Traverse list backwards

Print each index i and value x from the list items, from the last down to the first.

var i = items.length ;
for (var e in items.reversed) {
  i--;
  print("$i, $e");
}
for ($i = $#items; $i >= 0; $i--) {
    print "$i $items[$i]\n";
}
for(int i = items.Count - 1; i >= 0; i--)
{
    Console.WriteLine($"Index = {i}, Item = {items[i]}");
}
