Diseñe un algoritmo que le permita montar bicicleta y llevar en ella una carga desde la tienda hasta su casa.

Stella [2.4K]

Answer:

La fuerza se aplica en el lado opuesto de la carga.

Explicación:

Para andar en bicicleta y llevar una carga de la tienda a su casa, usamos tales reglas para llevar la carga de manera más fácil y segura. Si la carga es grande y está colgada en el mango derecho de la bicicleta, entonces la fuerza se aplica en el lado izquierdo de la bicicleta para mantener el equilibrio. Si no hicimos esto, la moto se irá hacia el lado derecho y el piloto sufrió el accidente.

Write a python program to read four numbers (representing the four octets of an IP) and print the next five IP addresses. Be sur

sdas [7]

Answer:

first_octet = int(input("Enter the first octet: "))

second_octet = int(input("Enter the second octet: "))

third_octet = int(input("Enter the third octet: "))

forth_octet = int(input("Enter the forth octet: "))

octet_start = forth_octet + 1

octet_end = forth_octet + 6

if (1 <= first_octet <= 255) and (0 <= second_octet <= 255) and (0 <= third_octet <= 255) and (0 <= forth_octet <= 255):

for ip in range(octet_start, octet_end):

forth_octet = forth_octet + 1

if forth_octet > 255:

forth_octet = (forth_octet % 255) - 1

third_octet = third_octet + 1

if third_octet > 255:

third_octet = (third_octet % 255) - 1

second_octet = second_octet + 1

if second_octet > 255:

second_octet = (second_octet % 255) - 1

first_octet = first_octet + 1

if first_octet > 255:

print("No more available IP!")

break

print(str(first_octet) + "." + str(second_octet) + "." + str(third_octet) + "." + str(forth_octet))

else:

print("Invalid input!")

Explanation:

- Ask the user for the octets

- Initialize the start and end points of the loop, since we will be printing next 5 IP range is set accordingly

- Check if the octets meet the restrictions

- Inside the loop, increase the forth octet by 1 on each iteration

- Check if octets reach the limit - 255, if they are greater than 255, calculate the mod and subtract 1. Then increase the previous octet by 1.

For example, if the input is: 1. 1. 20. 255, next ones will be:

1. 1. 21. 0

1. 1. 21. 1

1. 1. 21. 2

1. 1. 21. 3

1. 1. 21. 4

There is an exception for the first octet, if it reaches 255 and others also reach 255, this means there are no IP available.

- Print the result

Rufina [12.5K]

The best line to be added to the teacher’s lesson plan, which is supposed to emphasize the benefits of global communication, would be (D) learning in a global community enables you to expand your horizons and learn new languages.

The other options are not suitable because they highlight the negative side of global communications, which is not something that the teacher’s lesson intends to do.

Write a function named remove_duplicates that takes a list (of numeric and/or string values) and returns a new list with only th

Lorico [155]

Answer:

def remove_duplicates(lst):

no_duplicate = []

dup = []

for x in lst:

if x not in no_duplicate:

no_duplicate.append(x)

else:

dup.append(x)

for y in dup:

if y in no_duplicate:

no_duplicate.remove(y)

return no_duplicate

Explanation:

Create a function called remove_duplicates that takes one parameter, lst

Create two lists one for no duplicate elements and one for duplicate elements

Create for loop that iterates through the lst. If an element is reached for first time, put it to the no_duplicate. If it is reached more than once, put it to the dup.

When the first loop is done, create another for loop that iterates through the dup. If one element in no_duplicate is in the dup, that means it is a duplicate, remove that element from the no_duplicate.

When the second loop is done, return the no_duplicate
