Once the configuration step is over, the program then moves to a sample collection phase in which the

user either enters a new set of samples or an exit code.

$1)$ If a value is a non$-$negative integer, it is a threat level score for the current set.

$2)$ If the value is $-1$ then the sample input is complete and your code should evaluate this

sample set for a threat, print the result, and then begin to collect a new sample set.

$3)$ If the value is any other negative value then the program immediately quits $($by calling

sys$.$exit$())$ and any samples that are part of an incomplete set are discarded.
