design a stack such that getMinimum( ) should be O(1)

Creating a daemon in Linux
...where it was started + a newline.
Daemons work in the background and (usually...) don't belong to a TTY that's why you can't use stdout/stderr in the way you probably want.
Usually a syslog daemon (syslogd) is used for logging messages to files (debug, error,...).
Besides that, there are a few re...
Undoing a 'git push'
