The program valsort, included with the gensort tar file, validates the order of the records in the output file using memcmp ( ). If you sorted the records using a different sorting order, you should modify valsort to use the appropriate key comparison. The validation program also computes a checksum of the records and counts the number of duplicate keys. You should verify that the checksum of the output file(s) matches the checksum of the input file(s). You should report the checksum and number of duplicate keys as part of your contest entry.
