Cho các văn phạm: a) G = ( Σ , Δ , S, R ) với tập quy tắc sinh
R = { S → ABC, AB→ iADj, Dij→ iDj, DiC→ BiC, iB→ Bi, AB→ ε, C→ ε } với i, j ∈ {a, b}.
b) G = < Σ , Δ , S, R > với tập quy tắc sinh: R = {S → SS, S → aSb, S → bSa, S → ab, S → ba}.
c) G = < Σ , Δ , S, R > với tập quy tắc sinh: R = {S → aS, S → a | với a ∈ Σ = {a1, a2, …an}}.

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.
