Note the Sample output in 461 only demonstrate the formatting (not correct output),
since party of 4 clearly takes <60 minutes,
so we can schedule the part of 4 for bench 1 at time 0, and it will be still available at time=60 minutes to
be scheduled again.

The correct output to the sample input is the following.

I program in Java and I have had many TLE, after several hours and tests I arranged by redesigning the classes and using TreeSet to reduce the time of the searches.
But now I get WA, and I have doubts produced by the ambiguity of the problem
1 - the two-person tables can be grouped ?, I think not.
2 - are there some arrival time limit that produces the 'Impossible' result ? also I think not.

Thanks in advance
