Jim,
Here is my submission that ran in 70 milliseconds on my 5 1/2 year old
G4 450 MHz tower:
set cursor to watch
put the milliseconds into t
put fld "ChemSymbols" into c
put fld "dictionary" into d
repeat for each line L in d
if c contains char 1 to 2 of L and c contains char 3 to 4 of L\
and c contains char 5 to 6 of L and c contains char 7 to 8 of L\
and c contains char 9 to 10 of L then
put L & CR after o
end if
end repeat
put the milliseconds -t into t
put o into fld "Output"
put "time=" & t && "msecs" after fld "Output"
Cheers,
Glenn
Glenn,
Great solution!
At first I thought it would be slower than the one that most of us
opted for, i.e. test each condition sequentially and if the test
fails at any level go on with a "next repeat".
I thought RR would test all the conditionals in your handler (in
...and ... and...) before moving on to the next repeat, but Scott
Raney was too smart for that. Apparently, at the point where the
"and" test fails, RR decides there is no point in proceeding with
the others, so...... next repeat.
The speed is about the same for either method.
Jim
P.S. If you submit your solution to NPR and your name is drawm, you
are in danger of being called on Sunday for another test of wits. My
mind works too slowly for this kind of exposure.
