# Stars
#
# From: BASIC Computer Games (1978)
#       Edited by David H. Ahl
#
# "In this game, the computer selects a random number from 1 to 100
#  (or any value you set [for MAX_NUM]).  You try to guess the number
#  and the computer gives you clues to tell you how close you're
#  getting.  One star (*) means you're far away from the number; seven
#  stars (*******) means you're really close.  You get 7  guesses.
#
# "On the surface this game is very similar to GUESS; however, the
#  guessing strategy is quite different.  See if you can come up with
#  one or more approaches to finding the mystery number.
#
# "Bob Albrecht of People's Computer Company created this game."

# Python port by Jeff Jetton, 2019

# Porting Notes
#
#   The original program never exited--it just kept playing rounds
#   over and over.  This version asks to continue each time.
#
#
# Ideas for Modifications
#
#   Let the player know how many guesses they have remaining after
#   each incorrect guess.
#
#   Ask the player to select a skill level at the start of the game,
#   which will affect the values of MAX_NUM and MAX_GUESSES.
#   For example:
#
#       Easy   = 8 guesses, 1 to 50
#       Medium = 7 guesses, 1 to 100
#       Hard   = 6 guesses, 1 to 200
