Answer and Explanation:
#take input from user
n = int(input("Enter any number: "))
#sum variable to store sum
sum=0
#condition to exit from loop
while n!=-999:
#adding entered number in sum variable
sum=sum+n
#take input from user
n = int(input("Enter any number : "))
#print the sum
print("sum =",sum)
output:
Enter any number: 10
Enter any number : 100
Enter any number : -999
sum = 110
Answer:
Let our mask be 1010000...000. Notice that, if we apply XOR operation to any number with this mask, the first and third bits will be complemented and all other bits will be unchanged. Since for each individual bit, XOR with 0 does not change the value of bit and XOR with 1 changes the value of bit.
Explanation:
To give a hexadecimal number, we should know the number of bits in representation of number.
The correct answer to this open question is the following.
The regulation of security and trustworthiness on the Internet is likely to develop into more security practices that can guarantee people, the investors, the common citizen, that their information, transactions, and private life are protected. The government has to play a big and key role in demanding companies to install the proper security protocols in their systems in order to protect the information of their clients.
