Avoid executing code on module level as this prevents importing the module for testing. Especially infinite loops are evil.

# "In program Guess, the computer chooses a random
|
|
# integer between 0 and any limit and any limit you
|
|
# set. You must then try to guess the number the
|
|
# computer has choosen using the clues provideed by
|
|
# the computer.
|
|
# You should be able to guess the number in one less
|
|
# than the number of digits needed to represent the
|
|
# number in binary notation - i.e. in base 2. This ought
|
|
# to give you a clue as to the optimum search technique.
|
|
# Guess converted from the original program in FOCAL
|
|
# which appeared in the book "Computers in the Classroom"
|
|
# by Walt Koetke of Lexington High School, Lexington,
|
|
# Massaschusetts.

# Altough the introduction says that the computer chooses
|
|
# a number between 0 and any limit, it actually chooses
|
|
# a number between 1 and any limit. This due to the fact that
|
|
# for computing the number of digits the limit has in binary
|
|
# representation, it has to use log.
