Write to goofy@disney.com to get help on this assignment:
Me@myhome.it is my address, while OGRE@darkforest.net is
not mine, but Sherk's, so you shouldn't write to
ogre@darkforest.net
Both <liza@polito.it> and "pamela@polito.it" are fancy
Addresses (and you can write them as Liza@Polito.IT
or 'PaMeLa@pOlItO.IT'
ne deve estirpare gli indirizzi email, cambiarli tutti in minuscolo, togliere segni particolari come <> e "", e memorizzarli in un file di output, facendo attenzione a non inserire nell'output indirizzi email già presenti...c'è qualcuno che riesce a darmi una mano?
