In this task, you are given an input stream, and your task is to produce a grammatically correct version of the input sentence. The input to this task is a stream of words, possibly from captions generated by a speech-to-text engine, and the output is a grammatically correct version of the input stream. Stream words are in [] and have been separated with a comma. The sentence can contain words that have case, punctuation, stem-based, intra-word, and digit punctuation errors that need to be corrected. For example, the text should be uppercased/lowercased as per necessity (like the beginning of a sentence, proper nouns, etc.), and digits need to be normalized (6 as six and so on). Note that you don't need to normalize the years. You don't need to fully edit the sentences, if end of the input stream contains sentence fragments, keep them as is.

it's
pretty
rare
to
have
a
conversation
about
education
policy
in
which
the
word
"technology"
isn't
used
at
some
point.
Occasionally,
in
the
administrative
sense,
as
a
way
to
make
education
more
efficient;
but
mostly
in
the
classroom
sense,
helping
kids
learn.
Which
gets
us
to
Salman
Khan.
He's
a
former
hedge
fund
manager
turned
educator
as
the
founder
and
sole
faculty
member
of
the
Khan
Academy.
It
started
as
a
tutoring
service
for
his
cousins
on
YouTube.
It's
become
a
library
of
thousands
of
instructional
videos
on
topics
from
basic
arithmetic
to
organic
chemistry
to
the

Revolution
