Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer
oksano4ka [1.4K]

Answer:

The program in Python is as follows:

def get_user_values():

   user_values = []

   n = int(input())

   for i in range(n+1):

       inp = int(input())

       user_values.append(inp)

   output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

   for i in user_values:

       if i <= upper_threshold:

           print(i,end=" ")

           

get_user_values()

Explanation:

This defins the get_user_values() method; it receives no parameter

def get_user_values():

This initializes user_values list

   user_values = []

This gets the number of inputs

   n = int(input())

This loop is repeated n+1 times to get all inputs and the upper threshold

<em>    for i in range(n+1):</em>

<em>        inp = int(input())</em>

<em>        user_values.append(inp)</em>

This passes the list and the upper threshold to the output..... list  output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

This defines the output.... list

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through the list

   for i in user_values:

If current element is less or equal to the upper threshold, the element is printed

<em>        if i <= upper_threshold:</em>

<em>            print(i,end=" ")</em>

The main method begins here where the get_user_values() method is called

get_user_values()

Truck drivers probably can't see your vehicle if ______________.
Arada [10]
<h2>Answer:</h2>

Truck drivers probably can't see your vehicle if you cannot see them in their side mirror

<h2>Explanation:</h2>

In driving terminology there is a term called the bind spot. Blind spot is the area where the driver is not able to see the vehicle behind him and this area is present just behind the truck and very close to the gates of the car. Since trucks do not have the rare mirror therefore if a car is present in their blind spot they wont be able to see it. The driver behind the truck can spot it if he does not see the truck driver in the side mirror of the truck.

HELP PLEASE!!!! Which development method is best explained in this way: developing a system through repeated cycles and smaller
vlada-n [284]

Answer:

Incremental method.

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.

In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
