Problem Set Notes:
Revised wording in 6A:
``You should have noticed that the implacable searcher does well against the
random-answer hider. A more plausible random-location-hider picks
a location at random in the current interval and answers as though it were
at that location. While the random-answer hider answers "higher" with
probability one half, the random location hider is more likely to answer
"higher" when the interval above the split point is larger than the
Typo in Exercise 5: "naive-searcher" should be "random-searcher"
This is corrected in the ps file above.
In a number of problems we have left it ambiguous whether the range
(Ex. from 0 -> 30) includes the high value (30), and therefore how many
elements there are (30, or 31). Make a choice that makes the most sense
to you and tell us which one you chose.
