# 2) Sorting Test
#
# Sort an input file that consists of lines like this
#
# var1=23 other=14 ditto=23 fred=2
#
# such that each output line is sorted WRT to the number. Order
# of output lines does not change. Resolve collisions using the
# variable name. e.g.
#
# fred=2 other=14 ditto=23 var1=23
#
# Lines may be up to several kilobytes in length and contain
# zillions of variables.
# This implementation:
# - Reads stdin, writes stdout
# - Uses any amount of whitespace to separate fields
# - Allows signed numbers
# - Treats illegally formatted fields as field=0
# - Outputs the sorted fields with exactly one space between them
# - Handles blank input lines correctly
