Your program begins with a configuration step in which the user is prompted to input two values. The

values are read in one time, and are fixed for the remaining duration of the program. That is$,$ all the

sample sets are processed using the same configuration.

$1.$ First, prompt for the threat level threshold $($min$\_$threat$\_$level$)$ to determine whether a

packet is threatening. The min$\_$threat$\_$level is an integer and its value must be equal to

or larger than the constant MINTHRESH. If the input value is invalid $($Examples of invalid input

are $$hello$,5\mathrm{.}4,-2,$ etc.$),$ print a message $($The minimum level is

invalid.$)$ and repeat the request for the threat level threshold until a valid value is entered.

However, if the value is $-1,$ then exit your program instead $($by calling sys$.$exit$()).$

$2.$ Next, prompt for the false alarm threshold value $($false$\_$alarm$\_$count$).$ The

false$\_$alarm$\_$count must be a positive integer, and again prompt until a valid value or a $-1$

is input.

Note that min$\_$threat$\_$level and false$\_$alarm$\_$count are defined in the given template with

negative initial values. They both are expected to change during the configuration step according to the

user$$s input.
