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