Results for Exercise Sheet 4 (Compression)
Please read the instructions below, before adding something to the table!
1. Add your row to the table below, following the examples already there.
2. Use the template from public/code/lecture-04 and the original people.tsv. This way compression ratios can be compared and correctness ensured.
3. Provide the programming language and the specs of the machine you used in the same way as the examples already there. In particular, specify the processor frequency with exactly one digit after the dot, the amount of RAM as an integer, and don't provide secondary details about the processor. Just like you did for the last sheet.
