# Towers of Hanoi in sed.
|
||||
#
|
||||
# @(#)hanoi.sed 8.1 (Berkeley) 6/6/93
|
||||
#
|
||||
#
|
||||
# Ex:
|
||||
# Run "sed -f hanoi.sed", and enter:
|
||||
#
|
||||
# :abcd: : :<CR><CR>
|
||||
#
|
||||
# note -- TWO carriage returns, a peculiarity of sed), this will output the
|
||||
# sequence of states involved in moving 4 rings, the largest called "a" and
|
||||
# the smallest called "d", from the first to the second of three towers, so
|
||||
# that the rings on any tower at any time are in descending order of size.
|
||||
# You can start with a different arrangement and a different number of rings,
|
||||
# say :ce:b:ax: and it will give the shortest procedure for moving them all
|
||||
# to the middle tower. The rules are: the names of the rings must all be
|
||||
# lower-case letters, they must be input within 3 fields (representing the
|
||||
# towers) and delimited by 4 colons, such that the letters within each field
|
||||
# are in alphabetical order (i.e. rings are in descending order of size).
|
||||
#
|
||||
# For the benefit of anyone who wants to figure out the script, an "internal"
|
||||
# line of the form
|
||||
# b:0abx:1a2b3 :2 :3x2
|
||||
# has the following meaning: the material after the three markers :1, :2,
|
||||
# and :3 represents the three towers; in this case the current set-up is
|
||||
# ":ab : :x :". The numbers after a, b and x in these fields indicate
|
||||
# that the next time it gets a chance, it will move a to tower 2, move b
|
||||
# to tower 3, and move x to tower 2. The string after :0 just keeps track
|
||||
# of the alphabetical order of the names of the rings. The b at the
|
||||
# beginning means that it is now dealing with ring b (either about to move
|
||||
# it, or re-evaluating where it should next be moved to).
|
||||
#
|
||||
# Although this version is "limited" to 26 rings because of the size of the
|
||||
# alphabet, one could write a script using the same idea in which the rings
|
||||
# were represented by arbitrary [strings][within][brackets], and in place of
|
||||
# the built-in line of the script giving the order of the letters of the
|
||||
# alphabet, it would accept from the user a line giving the ordering to be
|
||||
# assumed, e.g. [ucbvax][decvax][hplabs][foo][bar].
