Why the output is reversed?

At 1:03 the output is reversed, why that happens?

It’s not reversed, it just appears to be. Or in other words, it was not reversed on purpose/predictable way. Maps don’t keep items in sorted order. If you print the map once again there is no guarantee that the order will be the same as the last time. Try it for yourself, make a map and print it a few times in a row.

Now I see, but when I try by myself it still comes out the same way I input. Anyway, for now, I know Dict doesn't have order and they can come with whatever order.
