I don't understand how should the output be written. Why
are there five numbers in the output? What do they mean?

Can anyone tell me, please? Thank you.

The number represent the room on the k-th floor where the
guy is at a moment of time. Initially k is 0. Because the
guy goes to next floor without changing it's room
corespondingly that means that when there appear 2
identical numbers on consecutive lines we know that he got
one flor up.


Ex
If the number of camere is 4 and the number of floors is 3
and we have output
3
3
2
1
1

it means that the guy followed this path:
 1   2   3   4   // camerele
---------------
| | | | |v| | |  // floor 1
---------------
|v| |<| |<| | |  // floor 2
---------------
|!| | | | | | |  // etaju 3
