Try stackoverflow.com.  They delight in problems such as these.

I store the original line with h, and then pull it back out repeatedly
with G to mangle it.
I got far enough to translate "first second ..." to "First s" with this:

h
s/^(.).*/\1/
y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
G
s/^.([^ ]+ ).*/\1/
s/^.([^ ]+)$/\1/
G
s/^.[^ ]+ (.).*/\1/
#y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
#3y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
s/\n//g

There's a couple problems.  (1) It doesn't handle the case with only
one word on a line, because it's hard to tell, later on, that I pulled
out the single word once already. (2) I'd like to put in one of the
commented-out y commands, but (2a) the first uppercases the entire
pattern space, and (2b) the second refers to line 3 of the entire
file, not line 3 of the pattern space.
