This program uses (7,4) Hamming Code to recover data that has been corrupted. In this particular case, corrupted emails are passed in and corrected to show their original messages.

Each codeword in the test files have exactly 1 error. This program determines where that error occured and corrects it.

This Perl script loads in the corrupted emails, finds the inavlid bit in each codeword, fixes it, and then prints the original version and the correct version to the console.

These are corrupted text files containing several hundred 7-bit codewords. Each codeword has exactly one error. When fixed by the above Perl script, they will print as legible email message.
