From the Maelstrom docs
Maelstrom nodes receive messages on STDIN, send messages on STDOUT, and log debugging output on STDERR. Maelstrom nodes must not print anything that is not a message to STDOUT. Maelstrom will log STDERR output to disk for you.
I am using
fmt.Fprint(os.Stderr, "Received message: ", msg, "\n") to print to STDERR but can’t find it. Does anyone know how I can log messages to better understand the protocol?
