Kent and Bob, Are you thinking of the first problem in Bentley's Programming Pearls? The original poster's questions sounds like it could be in that domain.
http://netlib.bell-labs.com/cm/cs/pearls/cto.html So I agree: the next questions we probably should ask the original poster: * Why are you trying to search for a number in those sorted integers? * Is there anything characteristic about those sorted integers that might be peculiar or useful? Do the numbers have "streaks"? Are the integers large or small? _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
