Write a program that uses a stack to test input strings to determine whether they are palindromes. A palindrome is a sequence of characters that reads the same as the sequence in reverse; for example, noon.
Answers
Answer:
Here the code is given as follows,
Explanation:
def isPalindrome(x):
stack = []
#for strings with even length
if len(x)%2==0:
for i in range(0,len(x)):
if i<int(len(x)/2):
stack.append(x[i])
elif stack.pop()!=x[i]:
return False
if len(stack)>0:
return false
return True
#for strings with odd length
else:
for i in range(0,len(x)):
if i==int(len(x)/2):
continue
elif i<int(len(x)/2):
stack.append(x[i])
elif stack.pop()!=x[i]:
return False
if len(stack)>0:
return false
return True
def main():
while True:
string = input("Enter a string or Return to quit: ")
if string == "":
break
elif isPalindrome(string):
print("It's a palindrome")
else:
print("It's not a palindrome")
if __name__ == '__main__':
main()

For the following scenario, indicate whether the action is a good practice or bad practice to safeguard your personally identifiable information.
Marina's personal computer requires a password to get access.
Answers
Answer:
This is most definitely a good practice to safeguard personal information. This way, people wouldn't be able to access her computer easily, since it requires a code that only she would know. of course, there is the possibility that someone can just guess or hack into her computer, but that's why computers usually have you create a unique code that consists of uppercases, lowercases, numbers, special characters, etc which would be difficult to guess. it's a good protection for anyone who wants to safely keep their personal information from everyone else.

Write a program get_price.py with a function get_price() that takes a dictionary of fruits as an argument and returns the name of the most expensive fruit. Each item of the dictionary includes: A key: the name of the fruit A value: the price of the fruit.
Answers
Answer:
The program is as follows:
def get_price(fruits):
AllPrice = fruits.values()
value_iterator = iter(AllPrice)
mostExpensive = next(value_iterator)
for item in fruits:
if fruits[item]>=mostExpensive:
mostExpensive = fruits[item]
fruitName = item
print(fruitName)
fruits = {}
n = int(input("Number of Fruits: "))
for i in range(n):
name = input("Fruit name: ")
price = int(input("Fruit price: "))
fruits[name] = price
get_price(fruits)
Explanation:
This defines the get_price function
def get_price(fruits):
This gets all price in the dictionary fruit
AllPrice = fruits.values()
This passes the values to a value iterator
value_iterator = iter(AllPrice)
This initializes mostExpensive to the first price in the dictionary
mostExpensive = next(value_iterator)
This iterates through the elements of the dictionary
for item in fruits:
If current element is greater than or equals most expensive
if fruits[item]>=mostExpensive:
Set most expensive to the current element
mostExpensive = fruits[item]
Get the corresponding fruit name
fruitName = item
Print fruit name
print(fruitName)
The main begins here
This initializes the fruit dictionary
fruits = {}
This gets input for the number of fruits
n = int(input("Number of Fruits: "))
This is repeated for every inputs
for i in range(n):
Get fruit name
name = input("Fruit name: ")
Get fruit price
price = int(input("Fruit price: "))
Append name and price to dictionary
fruits[name] = price
Call the get_price function
get_price(fruits)
Suppose a program written in language L1 must be executed on a machine running a program running in language L0. What important operation must take place
Answers
Question Completion with Options:
a. Translation of the entire L1 program into L0 code
b. Translation of the L0 program into L1 code
c. Creation of a language L3 that interprets L0 instructions
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Answer:
The important operations that must take place in this scenario are:
a. Translation of the entire L1 program into L0 code
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Explanation:
Translation enables decoding to take place. This means that the L1 program is decoded into a language that the L0 program can understand and execute. Without this translation, the higher level language of L1 will not be understood by the machine language of the L0 programs. Translation of a code creates a shared understanding, thereby easing program execution. Code translation is simultaneously accompanied by interpretation.
Genevieve is a student who attends classes at a campus downtown. She likes to study in the college's coffee shop, where she often accesses the Internet through the college's wireless network. Which network type is Genevieve using
Answers
Answer:
I'll let you make an educated guess off of this info! You always retain info better making an inference on a subject that you are having trouble with!
Explanation:
There are four types of wireless networks -- wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networks -- each with its own function.
wireless local area networkA wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.
wireless metropolitan area networkA metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).
wireless personal area networkA PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.
wireless wide area networkWireless wide area network (WWAN), is a form of wireless network. ... WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service.

The network type Genevieve uses is a wireless local area network.
What is a wireless local area network?
A wireless local area network (WLAN) exists as a wireless distribution procedure for two or more devices. WLANs utilize high-frequency radio waves and often contain an access issue to the Internet. A WLAN permits users to move around the coverage area, often a house or small office, while preserving a network connection.
Therefore, the correct answer is option (a) LAN.

Shawn's supervisor has tasked him with determining how the company can increase the security of its Wi-Fi. Shawn plans to present several options to his supervisor and ask her to check his work. Which of the following is not a strong security method? (Select TWO.)
a. Disabling SSID
b. WPS
c. MAC filtering
d. Setting encryption
Answers
Answer:
The not strong security methods are:
a. Disabling SSID
b. WPS
Explanation:
When you disable SSID, you only make your Wi-Fi secure for the less determined attackers. By disabling the SSID (network name), those who are less technically inclined are prevented from connecting to the network but, this will not deter a more determined and technically savvy adversary. The best two options are MAC filtering and setting encryption. WPS (Wi-Fi Protected Setup) enables the process of connecting to a secure wireless network from a computer or other device easier instead of making it harder.
