# this program reads a list of numbers from the standard input, with
# one or more numbers per line separated by spaces on each line, and
# prints the largest cluster of extension D.  The parameter D is a
# number that may be given as the first command-line argument.  If the
# parameter is not specified, the default value is D=10.  A cluster of
# extension D is a list of all the elements taken from the input list
# that are within a distance of at most D from each other.  For
# example, if the input sequence is 12, 2, 34, 7, 21, 24, 50, 45, -9,
# 7, 45, and if D=10, then the output should contain the numbers 12,
# 2, 7, 7 because those numbers form a cluster of extension 10, and no
# other cluster of extension 10 contains more than 4 elements.
