Explanation:

The principle of least privilege an important principle in computer security.
It limits the access rights for users and only grant them with the rights that are sufficient for them to perform their required task.
For example a user is granted privilege to execute a file or manipulate data or use only the resources that are required for them to perform a particular task.
This principle can be used only to limit and control access rights to system resources and applications.
The least privilege is beneficial as it reduces the risk of unauthorized access.

Write a program that accepts a positive integer N as command-line argument, and outputs True if N is the square of some integer,

Ann [662]

Answer:

In Python:

N = int(input("Positive integer: "))

if N > 0:

flag = False

for i in range(1,N+1):

if i * i == N:

flag = True

break

print(str(flag))

else:

print("Positive integer only")

Explanation:

N = int(input("Positive integer: "))

If the number is positive

if N > 0:

This initializes a boolean variable to false

flag = False

This iterates from 1 to the input integer

for i in range(1,N+1):

This checks if th number is a square of some integer

if i * i == N:

If yes, flag is set to true

flag = True

The loop is exited

break

This prints either true or false, depending on the result of the loop

print(str(flag))

If otherwise, that the number is not positive

else:

print("Positive integer only")
