Eat, Sleep, Spaghetti, repeat. This project is about learning how threads work by precisely timing a group of philosophers on when to pick up forks and eat spaghetti without dying from hunger.

• number_of_philosophers: 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.

• Test: 1 800 200 200. The philosopher should not eat and should die.
• Test: 5 800 200 200. No philosopher should die.
• Test: 5 800 200 200 7. No philosopher should die and the simulation should stop when every philosopher has eaten at least 7 times.
• Test: 4 410 200 200. No philosopher should die.
• Test: 4 310 200 100. One philosopher should die.

• 5 600 150 150. no one should die
• 100 800 200 200. no one should die
• 105 800 200 200. no one should die
• 200 800 200 200. no one should die
• 4 200 205 200. a philo should die
• 4 410 200 200 10. no one should die, simulation should stop after 10 eats
• Invalid Input tests with negative numbers and with invalid argv

• Test: 5 800 200 200. No philosopher should die.

• Test: 4 410 200 200. No philosopher should die.
• Test: 4 310 200 100. One philosopher should die.
