Answer:
ababababab
Explanation:
The code above is written in python and python uses indentation .So let me rephrase the code accordingly and explain what the code really do.
Note x and y is a global variable which can be used by any of the function declared. According to the question x and y are 2 and 3 respectively
The first block of code describes a function f1 without any argument but the code should return the string "ab"
def f1():
return "ab"
The second block of code defines a function f2 and returns the value of f1 multiply by x. This means you are multiplying the string "ab" by 2 which will be equals to abab
def f2():
return f1() * x
The third block of code declared a function f3 and returns the sum of f2 and product of f1 and y. using PEMDAS principle the multiplication aspect will be solved first so, ab × 3 = ababab, then we add it to f2 . ababab + abab = ababababab.
def f3():
return f2() + f1() * y
Finally, we print the function f3 value to get ababababab
print(f3())
If you run the code on your IDE like below you will get ababababab
x = 2
y = 3
def f1():
return "ab"
def f2():
return f1() * x
def f3():
return f2() + f1() * y
print(f3())
Answer:20*i
Explanation:
Because the size will expand as its being written out to then have i
You should state the language you're using in these types of questions; here's an example in C++.
bool onOff = true;
if (onOff)
onOff = false;
else
onOff = true;
Answer:
The AES decryption time is 8 minutes
Explanation:
GIVEN THAT:
The 1 GByte is equal to 230 bytes and equal to 233 bits
The RSA decryption time is calculated as = 233 / (100*230 )
= 83886. 06 seconds
= 23 hours
The RSA decryption time is 23 hours
The AES decryption time is calculated as = 233 / (17 * 230 )
= 481.81 seconds
= 8 minutes .
The AES decryption time is 8 minutes
