Hello,
I am an experienced Java software developer and I have worked on such projects before, solving this work sheet won't be an issue. I will use one of the algorithms you specified (SSTF, Scan, C-Scan) or a specific one if you want. As you can see from my profile I am the right person for this work. This shouldn't take longer than 48 hours from when you accept my bid.
You can expect top quality code from me, with comments and good solutions.
Feel free to message me with any questions you might have.
Best regards,
Nohus, Professional Java Development
