Project 3 test file explanation:


unsorted input file contains the following 1000 records in binary format:
999 999.0
998 998.0
...
2 2.0
1 1.0
0 0.0


the sorted output file contains the following 1000 records in binary format:
0 0.0
1 1.0
2 2.0
...
999 999.0



The big unsorted input file contains the following 1,000,000 records in binary format:
999,999 999,999.0
999,998 999,998.0
...
2 2.0
1 1.0
0 0.0


the big sorted output file contains the following 1,000,000 records in binary format:
0 0.0
1 1.0
2 2.0
...
999,999 999,999.0


Note that the binary files were generated on an intel platform.
If you try to interpret them on a different platform, you may see different values due to differing byte orders based on big/little-endian hardware design.
