[OSy] Results of task #4, opt B (labs)

[Vojtech Horky]

Dear all,
I have submitted results from the fourth task (second run) to SIS.

I am sorry for the delay. Because I was able to quickly check all the 
solutions during the labs there should not be any surprises.

Please, contact me ASAP if you find any discrepancies (e.g. you think 
your solution is correct, you sent it but fields in SIS are empty ...).

Thanks,
- VH
