This program is a simulation of the dining philosophers problem

"./philo(_bonus)" <nb_of_philosopher> <time_to_die> <time_to_eat> <time_to_sleep> <number_of_times_each_philosopher_must_eat>

• nb_of_philosopher : The number of philosophers and also the number of forks.


• time_to_die (in milliseconds): If a philosopher didn’t start eating time_to_die milliseconds since the beginning of their last meal or the beginning of the simulation, they die.


• time_to_eat (in milliseconds): The time it takes for a philosopher to eat. During that time, they will need to hold two forks.


• time_to_sleep (in milliseconds): The time a philosopher will spend sleeping.


• number_of_times_each_philosopher_must_eat (optional argument): If all philosophers have eaten at least number_of_times_each_philosopher_must_eat times, the simulation stops. If not specified, the simulation stops when a philosopher dies.
