By calling print_stats() before the exit of the program we can see that the scheduler does a fair scheduling according to tickets of the jobs.
For example when running
./lottery 1 100000
from command line, the results printed by print_stats() are
Stats:
[25]: 14.210 %
[100]: 57.180 %
[50]: 28.610 %
So we can see that there is a fair scheduling going on in this program.
We can add more jobs with insert(), and the program does not break working well with these modifications too.
