Answer:
C=D cause d spells dogs jk I really dont know
Answer: Following code is in python
n=input()
num='1'
while int(num)<=int(n): //loop from 1 to n
flag=1 //if an unequal element will be found it will be 0
l=len(num)
if num[0]=='3':
j=0
k=l-1
while j<k: //loop till middle of number
if num[j]==num[k]:
j+=1 //from beginning
k-=1 //from end
else:
flag=0
break
if flag==1:
print(int(num))
num=str(int(num)+1) //number will be incremented as integer
INPUT :
1000
OUTPUT :
3
33
303
313
323
333
343
353
363
373
383
393
Explanation:
In the above code, a loop is executed till num is equal to n which is entered by the user. num is treated as a string so that to ease the process of checking first character is 3 or not. If it is 3 then another loop executes which checks if an element from starting is equal to the corresponding element from the end. If an element is not equal then the flag is changed and then we break out of the loop and prints the number if the flag isn't changed.
Assuming the data was encrypted with YOUR public key, you'll need YOUR private key to decrypt it. That's answer e.
a and b are not solutions by themselves, of course you need to use the decryption algorithm, but a key goes with it.
c would be about symmetric encryption, but this is asymmetric, so different keys are used for encryption and decryption
d is possible, but it would mean anyone can decrypt it (after all the key is public), so then there's no point in encrypting it in the first place.
So e is the only logical answer.
