How Did Vimar Germany Get Out of Hyper Inflation?

The wimar republic cured their initial round of hyper inflation in 19 23 by getting rid of the german papier mark and replacing it with a new currency called the renton mark. Another occurred just after world war two when the allies were running the german economy, and they'd imposed a bunch of policies that caused inflation to go out of control. People stopped using money and reverted to barter as a means of economic exchange.
