Answer:
The result of the following code will be 9
Explanation:
There are several operators used in Python to do mathematical calculations.
** operator is used for exponents.
i.e.
a ** b mathematically means a^b
Here in the given code
3 is assigned to numA and 2 is assigned to numB
Result will be equal to 3^2
Hence,
The result of the following code will be 9
Answer:
def insSort(arr):
ct=0;
for i in range(1, len(arr)):
key = arr[i]
j = i-1
while j >=0 and key < arr[j] :
arr[j+1] = arr[j]
j -= 1
ct=ct+1;
arr[j+1] = key
return arr,ct;
print(insSort([2,1]))
Output of the program is also attached.
The answer is encryption
steganography would be hiding data, like in an image
digital forensics is the analysis done after an attack
and the last one is a security standard
