Or a set of tuple (p, id) where p is the priority and id the process
number (= arrival time).
Then you sort lexicographicaly first by increasing priority and second
decreasing id to have FIFO for equal priority.

And I think a less than 10 lines O(N ln(N)) re-implemantation or
priority queues would
give you good result at your competitive exam !
 
My two cents,
Christophe
