A simple answer in SuperMarioLang. The only command that gets executed is `:` which prints the value of the currently pointed memory position (0) as a number (initially 0). The second command `%` never gets executed as Mario (the command pointer) falls because there is no floor under him, so the program stops. The average between `:` and `%` is `0`.
