Hello!
Shan Jiang

how do you call the set with +?
Justin Wang
14:49
i don't know if you've said before, but is space considered a letter in the alphabet
Henry Moore
15:11
I think it's just a symbol
Westin Montano
15:52
L is a SUBSET of sigma star
Justin Wang
16:57
yea
Aaron Geesink
20:35
whould the set of all legal English sentences, books, phrases etc. that are formed from English words also be part of the English language?
Westin Montano
21:37
no because the alphabet doesn't contain spaces
Westin Montano
21:45
or punctuation
Henry Moore
22:59
I think it would because the set of legal C programs is included and C programs have spaces
Westin Montano
23:48
But English's alphabet doesn't contain spaces/punctuation
Westin Montano
24:35
not sure what's included in C's alphabet tho
Marco Baez
26:35
ahh like 0 vs null?
Garrett Geesink
28:30
We can define a language however we like.A language can be the set of all English words, or it can be the set of all ascii characters that fit in a tweet.
Garrett Geesink
34:36
can epsilon be part of an alphabet?
Justin Wang
34:48
if something is an alphabet, it is a language right? since language is a subset

Justin Wang
46:07
if you cannot reach from start
Justin Wang
50:54
doesn't this check if there is an ing and not that something ends in ing
Boning Li
51:32
^
Ryo Kanda
52:55
imagine string "Inga" it did reach "ing" state but since it saw "a" it returned to nothing state
Justin Wang
54:42
just need one more state like saw space or something to check end
Thomas Henningson
55:22
no if theres a letter after it goes back to the beginning. it does check if it ends in ing because it will be in the last state once the string ends
Justin Wang
55:46
so we run it until the string ends and not the first occurrence
Thomas Henningson
55:53
yes
