Consider the set of all strings over the alphabet { a, b, /, . }{ a, b, /, . } that represent an ri (resource identifier). an ri is a non-empty sequence of forward-slash (//) separated non-empty strings composed of only the symbols aa and bb. the first string in the sequence may optionally be the .. symbol instead of a string composed of aa and bb. each string is separated by only one slash, and there are no slashes at the beginning or end of the sequence. write a regular expression, conformant with the syntax restrictions given at the top of this question, describing the set of strings as given above. write a (right) regular grammar describing the same set of strings.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
